Elliptical Mass Bias
« on: December 31, 1969, 06:00:00 PM »
This ball is Track’s introduction into the mass bias core technology market. It seems that every mass bias ball up until the EMB has had the same characteristics. They all hooked and stopped, some further down the lane, some at your toes; but they all hook and stop, because the bias makes them stand up too quickly. Track has been working on a core design that would allow the ball to hook to its maximum potential then continue along that path, while retaining energy! Track’s CATS results support this. From exhaustive research, Track has found that the friction levels at the 48’-52’ part of the lane is where balls burn up and thus, do not strike. The uniqueness of the EMB is the placement of the weight blocks around an elliptical core body. In addition to a top and bottom weight block, Track strategically placed a third weight block (flywheel block), which affects the ball’s performance at the critical 48’-52’ spot on the lane. With other balls, when the ball begins to lose energy and starts to roll out, the friction numbers begin to dip.  With the EMB however, the flywheel block maintains energy longer by kicking in when the ball begins to roll end over end, as it does when it rolls out. The flywheel kicks in similar to overdrive. Another important factor differentiating EMB from other mass bias balls is the fact that the mass bias (spin spot) only moves about ½-¾ of an inch after drilling! The reason the EMB is so different is the strength of the mass bias, which is about three times, and in some cases, four times stronger than most mass bias balls on the market today! It stays where you put it after you punch the holes in it, even after you add balance holes! The specifications are: Ball Construction: Multiple-Density Five-Piece Design; Backend Rating: 9 (On Track’s Scale of 1-10); Hook Rating: 20 (On Track’s Ball Reaction Chart); Flare Potential: High; Core Design: “HyperActive” Technology; Radius of Gyration: 2.536; Differential: 0.051; Cover Stock: “ProTraction Plus”; Color: Plum w/Silver logo fill; Finish: Polished; Pin Placement: 0-5 inches; Hardness: 76-78; Available Weights: 14-16 lbs. (“Multiple Density Five-Piece Design”), 12-13 lbs. (High Performance Core 2 Technology).

I just picked up an EMB last weekend and bowled on several different conditions with it. It is drilled with a 4" pin to pap (pin above and slighly right of ring finger), 1/2oz finger weight, small balance hole inline with thumb hole to promote backend. I am a medium speed player with a medium amount of revs. I found that in box conditions on heavy oil I did not have the revs to get the ball to hook much, had to play mainly down and in. The ball had to much overlap with my pearl Stomp as far as reaction so I sanded the surface to 400 grit. The ball played much better in the soup giving me a lot more boards in the back than my Stomp.
    I shot the sanded EMB on a drier shot than I thought would have been possible and had great results. The powerfull core allowed me to move very deep (something I dont do often) and play an extremely tight line pitching the ball over the fifth arrow out towards the ten pin and back. The ball never flipped hard but instead made a nice turn and continued to drive through the rack. This kind of shot was too much for the Stomp which would make it back to the pocket but would not have the energy to carry the ten pin. The EMB also recovered well when I missed right. It would hook back and not roll out like my other equipment would. In fact I have yet to get the ball to roll out it just doesnt want to quit.
     I think for me this ball is going to rule on medium conditions and house shots (which I face most). I think for us lower rev players though, this ball is not going to be a bigger oiler. We will have to hope that the EMB II will have a stronger cover, however, I think everyone will like the powerful motion this ball posseses.

emb box specs
15# 4oz
pin 2-3" (2 1/4")
top weight 2 3/4"
polished

after drilling specs for right hander:
4 1/4" pin to axis point (pin under ring finger)
3 3/8" cg to axis point  (cg kicked out)
1/4 oz finger weight, 1/2 oz positive side weight
with balance hole 6 1/2 from mid grip line
small emb logo placed in the 11:00 position

  i am right handed ,roll about 18 mph with a 45 degree axis rotation with a medium hook. tried the emb in box condition it's polished state on a medium oily condition and got that over under reaction when it got to the dry backend part of the lane. light scuffed the emb using a gray scotchbrite pad on a ball spinner to take some of the polish off to give the emb a little more ball surface to work with so the emb surface has polish with a slight dull haze.
 tried the emb on a medium and medium oily condition since the light scuffing and it's been a monster ever since. the roll is more predictable, great recovery and if it gets near the 1-3 pocket it's just blows the pins away. i have tried other track particle balls in the past
but the emb has to be the best of the track particle bowling balls so far.

16 lb 2 oz out of the box
2 oz top weight
pin 3 inches out

Drilled 4 x 4 1/4 with the middle of the small EMB logo 3/4 inches to the right
of my grip center.
Ended up with 1/4 ounce side weight and 1/8 ounce finger.

Ball speed 16-17 mph medium revs.
Lane condition is 34 feet  crowned out side the ten board and the lanes are stripped prior to the 1st shift shot, all wood lanes.

1st set out in a league where you bowl 2 then switch pairs and bowl two more after getting better timing 11 in a row, ten pin followed by another ten in a row. Nothing hits like a new ball but the carry percentage with this ball is so far amazing.  

Compared to my Rock On drilled 3 3/8 x 3 3/8 this ball clears the heads and the midlane even after some burn up of the shot. It starts its move farther down the lane and is more of an arcing move even on the fresh strip.
The overall hook difference is 2-3 boards at best between the balls, but after throwing this one side by side in practice for the shot I'm bowling on the Rock On is up for sale. The Rock On is a great ball but if you are bowling on a condition where you need help clearing the heads and mid lane with a more forgiving even arcing shot and do not have too much hand this is the ball.

Another bowler in the league who has over fifty 800's and has won the Super Hoinke had one that was drilled nearly identical to mine but, has monster revs and had to put his up it was just too much ball on this conditiion for his game.

This ball has been gone through a shake down.  Fun ball.  Great area and strong hit.  the way the ball revs is like the synergy ets.  remember that ball?  It was track's first ball to retain energy.  but this ball has awesome hit.  and i throw a 14#.  the young guns today do realize that you dont need a 15 or 16 pound ball to strike.  bowlers are amazed that i throw a 14 hit and carry like its a 15 or 16.  This the BEST ball Track has come out with.  Wonder what they are going to come out with this time?

We have only drilled one of these balls but the results have been very positive.

  We tested the ball in it's out of the box condition.  The drilling had the pin 4 1/2" from the p.a.p. and the c.g at 1/2 positive.  This label type drilling left the EMB logo at 45 degrees.  

  The lanes (synthetics) were oiled 35 feet and had light play ahead of our tests.  We had read that some people had experienced over/under reactions with the EMB so thats the first thing we looked for.  Our tested is a stroker who has 19-21 revs at 17mph.  The EMB got down the lane in great shape wich wasn't surprising, made an arc shaped move and continued through the pins strongly.  From this angle (13 to 7) the carry was very strong in fact, the tester commented that this ball gave him the "securiy" of knowing that any flush pocket shot was going to carry the corners.  With the back ends clean it was tough to measure the track flare but we estimate it at 4 to 4 1/2".  We then tested the EMB on some pairs that had not been stripped or oiled in a few days.  These lanes had more carry down and a dryer track up front.  We moved deeper and were targeting 19 to a break point of 12-13.  The EMB still got down the lane but wasn't getting around the corner well enough.  Once we tightened up the line (crossed fewer boards) the EMB began to crunch the pins again.  We did not at any time test the EMB with a dull shell, this being June it's tough to find enough oil to make it worth while.  At no time during the tests did we ever experience any over/under reactions.

  Overall, we liked the EMB as a powerful piece for medium to heavy oil. (depending upon how it reacts with the shell dull)  This is premium performance at a premium price.  What we didn't like had nothing to do with the ball itself but rather the promotional materials (drilling instructions) that came with it.  Some people may not get the most out of the EMB because they will feel restricted with thier drilling options.

  We also would like to make mention of the EMB's advertised roll out combating core.  My personal opinion is that every ball stops hooking, it's just a question of when.  Although this ball is very continuous, it will not solve roll out trouble for anyone who hasn't found anything else that does.  That is, if you are bowling on dry lanes and have slow speed this ball will stop hooking too soon, similar to other particle balls.  We should mention that at 17mph we could not detect the stop point on any shots we threw with the EMB.  Again, we liked the ball very much and found it to be both very powerful and very continuous.

Lanes: Wood, Oiled about 38 Feet Christmas tree pattern with the last 5 boards thickly oiled.
Lanecondition: Med.Oil to dry.

Bowling style: Tweener but can play straight up or a deep swing line.
                       Fast speed, medium revolutions.

Ball: Elliptical Mass Bias with 2 3/4" Pin out, drilled 3 1/2" X 5", EMB Logo 45° with 2 oz. of top weight. Leverage layout with semi-arc(because of the EMB Logo placement).

Assessment: The ball in the box condition was great for the lanes I was using it on. It made a nice little break about mid-lane and continued to move into the pocket with ease. The results as long as it didn't come to high in the pocket were great(strikes). Although when it came to high it left those ungodly splits( 4-7-8 6-10 or something worse). So make sure you come in to thin rather than to high. Actually I wanted this ball for oily lanes so I scuffed it up lightly with a green Scotch-Brite. The result from a light scuffing was unbelievable it took off very early and didn't quit. I even slowed my ball down quite a bit to see what this baby can do. I was standing 26-28 and throwing about 10-12 and it came back every time with a very readable arc just like I wanted.  

I will be writing this ball up again at the end of July or beginning of August because the lanes where I bowl will be replacing the wood lanes with synthetics ones. But I'm pretty optimistic that the EMB will move just as effectively on these new lanes as well.

About drilling this ball:  I thought there was something very special about this ball in considering the drill pattern to be used. Well after writing e-mails here and there. I met our driller here and told him that people were having problems drilling this ball. Well after about a half-hour of figuring out what to do. We seen that just taking a normal drill pattern from an Enforcer and making sure the EMB was in the right spot according to the specification sheet enclosed and then punching it up there is absolutely no problem in drilling this ball. Granted there are maybe some exotic drillings out there that will not fit this ball, but there is also no big difference than drilling any other ball.

I want to thank Werner Prietz for his help in drilling the ball and Buddies Proshop for their help which I asked for when I asked for it (per E-Mail).

Way to go TRACK !! Keep it up,I'll be looking forward to your next release.

Out of box ball-pin 2-3",31/4 top weight.Lane condition 2nd shift hous condition-oiled to 32+buff & carrydown.I drilled this ball 5" pin below ring finger with Track drill for early roll.The rev rate is high with this drilling,but the ball still went long & broke extremely hard!the laydown point was around 20 with the ball out to around 8 at 40 ft,it just turned the corner & did not quit!The stike percentage was good & the hit sent messengers very low!overall a 9 out of 10 for Track!! I can't wait to try the pearl!!

The EMB has been out for a while now and has generated very little posts here so I thought I would post another. I cant remember my exact specs right now and it really doesnt matter for this review. I will say generically that I am a medium speed, medium revs player. I also realize that this ball is now available in some other flavors, but dont count out original.
     First off, the EMB is NOT a hook every board of the lane kind of ball, but believe me it has plenty. There are already too many balls out there that just plain hook to much (yes there can be too much). This ball is just right for all but the most flooded conditions with my style. I dont see those conditions often so this ball works great for me. The EMB is also good even when the lanes get drier (such as 2nd shift).
     I didnt like the box condition, so I sanded mine. This made the ball not only cover a couple more boards, but made its reaction extremely smooth. I never have to wonder what the EMB is going to do...it just makes a nice smooth arc to, and through the pocket. It carries the entire rack better than any other ball I have. It carries the corners great except if I miss my mark and tug it inside. The ball will usually sit right to the pocket but will ping tens, but that is my fault, not the EMBs. Most of my other equipment with a similar shot will jump through the nose leaving a horrendous split, so the EMBs smooth reaction is real bonus here. Anywho if you actually read this and agree or disagree with anything I said I hope you get off your butt and write a review of your own...it is a free country...STILL!!!

Lanes: Synthetic, Oiled about 38-40 Feet Christmas tree pattern.
Lane condition: Heavy Oil to Med.Oil.

Bowling style: Tweener but can play straight up or a deep swing line.
Fast speed, medium revolutions.
Ball: Elliptical Mass Bias with 2 ¾“ Pin out, drilled 3 ½“ X 5“, EMB Logo 45° with 2 oz. of top weight. Leverage layout with semi-arc(because of the EMB Logo placement).

Assessment: I’ve altered the surface with Scotch-Brite and it seemed to do the job. The ball took off like expected hit the pocket hard and there was a 70% chance that one pin would be standing, mostly 10-pins but alot of 8’s as well. Tried changing the line, speed and release but nothing seemed to get rid of this. So I polished it up once more and all of a sudden the pins were flying again. But on heavy oil a straight up shot from 1 better be made on clean backends or it will never make it to the pocket. So I think I can safely say with the layout above, bowl with this one , after the lanes brake down or on medium oil.

Maybe with another layout and style this ball would move better on other conditions.
I think that I’d give this ball a 8.5-9.

Best ball ever. Tweener style bowler. Mine is drilled with the pin right next to the ring finger, driiled for length, zero imbalance and it hooks more than any other ball I have (X-It, Champ, Ti Boss II, Matritx, Extreme or Total Chaos). Wanted it to be similar to the Violent (no not violet) 3D hammers, and it is a perfect match. Long, even I can play from deep inside, miss outside, not put any hand in it, and it still recovers. It is not what you would think, it does not overreact, but I do now have an issue with the middle of the back row because it hits like a truck. 1-10, its an 11 no joke!!

TRACK HELL YEAH

EMB
Lanes: Synthetic, Oiled about 38-40 last 5 boards med.oil
Lane condition: Heavy Oil to Med.Oil.
Bowling style: Tweener but can play straight up or a deep swing line.
Fast speed, medium revolutions.
Ball: Elliptical Mass Bias with 2 ¾“ Pin out, redrilled 3 3/8” X 3 3/8“, EMB Logo on Grip center line with 2 oz. of top weight.

Assessment: After redrilling this ball, I started out bowling it exactly the same as before. This time the reaction was more aggressive obviously but also the carry was much better. First three games with it bowled a 695 with ease, BUT in heavy-oil with my release it was to squirty. Then I decided to give a 600-Grit finish that really worked but the coverstock didn’t seem to stay that way, after 10 games or so it was back to 800-100 grit.

Brenton Davy maybe right, with a drilling that rolls this ball immediately and continuously throughout the entire run of the ball would probably the best, because I’ve never seen this ball rollout.

For what it’s worth I’ll give this ball after two drillings and different surfaces a 8.5. It’s now polished and being used as my dry lane ball, because like I said it NEVER rolled out.

Got this ball used, thumb pluged, and layed out w/my favorite drill set up w/ no extra hole and the emb pretty high above the ring finger. This ball has desent lengnth, even when poilshed it doesn't go down very far, but when it turns, it turns, maybe its just the way i throw it on differnent conditions, but for me sometimes it rolls then snaps, other times snaps then rolls. Always hits the pins hard and sends them flying. My most hooking ball by far. Rolls out on dry, but so do all other partical balls.
The pleasure has been yours.
The great one

I purchased this ball once it first came out.  It was 16 lbs, had a 2-3" pin out distance, and the top weight ????....

I had it drilled label on the thoughts it would be a big hooker.  It wasn't, but it was strong enough to play on any house condition.  I shot my only 300 using this ball and I was playing 15 to 10.  For me this ball worked well on all varieties of medium oil, and even with some carrydown too.  The only time I needed to put this ball away was on drier or heavier patterns.  I sold the ball to a friend who was in dire need of something better.

I just got this ball Fri. nite in used condition. Didnt know what to expect. Had a doubles tourny yesterday and the lanes were soaked. This ball is awesome. Hits hard and drives all the way through the rack. Carries great. Great ball. Oh. i bowled a 257-228-238=723
