Elliptical Mass Bias
« on: December 31, 1969, 06:00:00 PM »
Ball NPS Score: Not Available
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 got my EMB drilled up Thursday and had a chance to use it last night.  Its drilled up with the EMB (small logo) in the upper right Quadrant half way between the center line and mid grip line.  The pin is 4 inches from my PAP with the cg under the ring finger 5 inches from the PAP.  Games of 202, 268, 276 last night.  Awesome ball carried whenever hit near the pocket light carry is good high hits trip the 4 and pocket shot blow everything off the lane.  Ball is very versatile wherever you like to play.

Me: Lefty, 18mph ball speed, forward roll and low to medium revs

EMB drilled label, 0 finger/thumb weight and 5/8oz + side weight, 3" pin 10 c'clock beneath fingers, CG below grip mid line, 1" out from grip centre line, no balance hole. EMB logo is 1 1/2" above the grip mid line for arc reaction.

This is supposed to be the arc drilling!!!  This polished particle ball just skids and then flips harder than any other ball I have ever thrown.  I thank the lord I didn't put the flip drill on it.  This ball gives such a strong backend reaction that when it appears to have no hope of making the recovery to the hole it just blasts back from seemingly too far out and rips the rack.  This is not a soft hitting ball, indeed it is so powerful that messengers are common even for my release which has softened with age (42 years old).

Caveat: this is not a reverse block ball, but if you have area it will read it to perfection.  I can't think of a ball that will maximise your scoring potential on a high scoring condition more than the EMB.  It is clean thru the heads and reads the condition to perfection.  It is a matter purely of find the oil line and have fun.  Roll out is greatly reduced, especially in box condition, but it will make the best oiler yet if dulled.  I expect that to be the case at the upcoming Australian Open.  Will review it again after that (if I get to use it there).  Meanwhile as the drill specs say in step 5....."layout span, drill holes and have fun!"

You will with this one

Track (EMB) Elliptical Mass Bias-
Ball info- 16#, CG to Pin is 5 3/8”
Drilling(RH)- Pin 3 7/8” from axis (Pap is located 5 7/8” >5/8” ^) above and right of the ring finger, CG is 6 1/4’ from axis located 2” below the center of the grip.
Cover stock texture- Factory polished and scuffed.
Lanes/conditions- Brunswick Pro Anvil, Approx Heads 20units 8 to 8 and 17units at 2 board(left side was 11units) pattern going to 41ft.
Lane play- Was tried from 12 to 20 board at the arrows.This seemed the best area for the conditions so far.
Review-Polished or scuffed the EMB was clean thru the heads with a powerful turn on the backend. Its has good recovery where other balls labored to come back,  the EMB would wind up and make the turn. Tracks flywheel weight block idea looks good and I expect to see it show up again. Deflection was good also.With a little area to work with this ball is a winner and has a high potential.
With carry down and/or dirty pin decks,the polished EMB still made the turn and drove.
But would would start leaving 10pins or wash outs. Scuffing the EMB helped solve this with better control and I recommend a scuffing or a light sanding for the surface if playing fresh oil or a wet/wet condition. Should be a good oiler with the right dull texture. Polished on shorter patterns or conditions with good backends or patterns starting to break down it seems to work good. Its stays in play longer than I would have thought. Just make sure to keep your speed constant and give it some room.
The ball holds pretty good on pulls, but depending on the condition it might cross Brooklyn or it can drive thru the head pin for a split. If just right of the head it should carry a strike.

Tracks new EMB has all the makings of a house condition go to.
I drilled mine 5 by 5 1/2 and I get better than average length
with an arching backend. Ball reaction is very readable and can
be used on a variety of conditions.

Being a lefty it took me a little while to line this baby up.  Due to the EMB marking being to the right of a line drawn through the pin and cg. The EMB marking is above the pin unlike other bias points being below the cg.  The cg ended up being on the centre of grip (5 1/4" from PAP) and the pin was 4" from PAP. I didn't get to use it on a house condition and took it straight to Malaysia for the Malaysia International Open.

Kegle did the lanes and the guy there stated it was the hardest pattern he could put down without putting down a reverse block.  The pattern was 37ft in length with ultra clean backends after the wash.

I am a lefty with medium rev's bowling at about 15-16 miles per hour.  I can tell you that I only used this ball about 10 shots in Malaysia and 9 of those were in practice.  It wasn't the length that was the problem it was the dramatic right hand turn when it hit the backend.  This ball was jumping at least 12 boards at a time and the chances of me controlling it on a fresh condition was impossible.  I left splits I never thought possible.  I put it back in the bag and waited until I got home.

I let some other lefties use it back home,  a lower rev person than me who had no problems in turning it (not much deflection when it hit) and a another lefty who hits it harder than me on a ditched house condition.  The guy in league was using a Red Alert Zone and swinging it from 8 out to the edge.  I gave him the EMB to use and after some stray shots found his mark, 16 board out to the edge.  I couldn't believe how much more this ball turned down the backend.  It appeared to accelerate when it hit the backend and did not deflect very much at all.  Very impressive and to date this ball has only left me with 2 seven pins (got to be a good thing).

1 week into having this ball I have elected to take the surface to a 1200 sheen finish.  What a relief!  This ball is definitely more controllable now and has cut back the violent hook I was experiencing before. This ball still goes long and still turns pretty hard without rolling out.   I recommend anyone who is having troubles bowling with this ball to play with the surface a bit.  It has made a considerable difference to my chances of using this ball from game 1.

This ball is a great addition to the TRACK family and I wouldn't be surprised if TRACK brought out another with the same weightblock, maybe a pearl pro-active or something.  This ball takes a little time to get use to but when the surface is fixed up and tune to your specific needs, it is awesome.  Thanks to Brando from brandosproshop.com.au for drilling this baby.  9/10.

Have now used the EMB in two different houses, and here's what I saw:

ME: PAP: 4 3/4 over, 1/2 up, average speed and revs.  

BALL: Pin: 2 1/2 inches, Top weight: 3 oz.

Drilled the ball with small EMB logo above the pin for good length and sharp backend.  Wanted this ball to combat carrydown and produce a reasonable carry angle.  First house, ball carried great, but was not very sharp at breakpoint.  Second house, much sharper backend, almost unplayable, break.  This leads me to believe there was some carrydown in the first house, which is what the ball was purchased for, and it handled that great.  The ball hits very well, carries excellently, and thus far I am very pleased with it.  Great ball when you need something you can send out, and can be confident it will come back.  Great job Track!

This is probably the best ball track has put out in a while.

But as Bowling this Month said when you can not keep it in the pocket you need to change. When you can keep it in the pocket the strike percentage is over 90 percent for me.

Because I am low track play my pin, cg and emb spot is different than most poeple. But I drill it to go about a little more the half way and break smooth and it works for me.

So I suggest everyone try their own way and have fun with it

This ball was ordered as follows: 16 lbs. 3" Pin, 4 oz. top weight.
the layout of the ball is as follows (I'm lefty): Pin 3 3/8" from PAP with the Pin directly left of my ring finger, CG 1/4" left of Grip Center, small EMB mass bias logo placed in the top left quadrant, near Grip Centerline, after drilling there was maybe 1/2 oz. top weight remaining. The Pin layout is leverage, but the CG and mass bias, according to the drill sheet, were set up to promote length and strong arc. The ball comes factory polished and was left that way. Analysis: on most house shots, which are tailored to help get the ball to the pocket, I could play two shots: from 15-17 board out to anywhere near the ditch, firm speed, and flip hard around the ball, and watch this thing go longer than I thought possible, and then just completely turn right,flop onto the 3rd flywheel weight puck, and drive hard with no rollout through the pocket. The second shot was from 15-17 out no further than 10, without hitting  on the ball. I was surprised to see that the ball would hold the line as well as it did, and kept expecting it to jump hard. This wasn't the case. This ball hits good; I've thrown balls that hit harder, but the pins stay low, and the carry is outstanding. I don't think that this ball will play well straight down and in, because it'll flip too hard too early. I also cannot honestly evaluate this ball on a heavy oil condition, although with the polished coverstock, I would guess that the movement would tame down. If you bowl on a condition where you can swing, and have some hand and ball speed, this thing will flat out roar. This ball will definitely make the trip to Reno!

Sorry for the Delay on the Review, thought I had already reviewed this ball.

When we received this ball, we also received a brief packet of information on how to layout this ball.  This is a completely new idea in bowling with the Ellipitical Mass Bias being located in the finger quadrant.  With a new concept comes new drillings.

We laid out a couple of these balls, and we placed the EMB at different degrees from the grip line.  One was a 30 degrees from the grip line on the positive side, and another 45 degrees.  The 45 degree layout produce more skid/snap than the 30.  I am sure that there will be a lot of drilling for this ball as time passes.

I on a scale of 1-10, I would give this ball a 6.  The reason it is so low, is because it is not driller friendly, and can result in bad reactions.  We have also heard that drilling sheets have not been included in every ball.  This ball is a great ball when laid out properly.  A different reaction from this ball will give you something different on those tougher shot.  You can change the surface easily to meet each bowlers needs.

If you have any questions, please email me at Bill@buddiesproshop.com.

Thanks

EMB By Track

Bowler style:  Cranker (High rev, med ball speed)
Lane: 35ft oil (single oiling) buff backend
Drill: 45 degress from grip
Rating: ? see below

 Drilled with the EMB 45 deg. from the grip. Tech. that was supposed to produce a lot of skid and strong back end snap.

  The skid was good on that layout but there was alot of ball wobble towards the end and it did not snap as strong.

  My driller and i spent a long time trying to figure out how to drill this ball and we still experienced the wobble towards the backend. It was not as conotrollable as my other balls like the trauma, eraser or the command zone.

  Not to take anything away from this ball but this ball has huge potential to be as close to a one ball arsenal IF drilled correctly. It was not very user friendly when it comes to drilling. If your driller is not VERY familiar with your bowling style, suggest you try other balls.

  We are still experimenting with other layouts to suit but we do see great potential. Because of that, we dont think it would be fair to rate this ball. Will give more feedback when we are able to.

Hi peeps! Just got my EMB drilled today. Drilled it with the small emb logo one inch to the right of my centerline, with the pin almost next to my ring finger. The cg is close to my center of grip.(like a 2 o'clock) I used the ball in a local tournament here. It's one leg of our national tournament circuit. The lanes were oiled 33-38 feet, buffed to 40, with an out of bounds past the 7 board. The EMB moved like a normal reactive, but snapped harder. I noticed that the ball would rev up more as it entered its roll. It hits hard, but not as I expected it to be. I just got used to Track putting out hard hitting balls that it may have put my expectations a lot higher. It may be due to the carrydown present on the lane, but it hit just like my avenger.(which hits hard already) Left a couple of solid tens, and a solid eight, then a half pocket seven. Overall, it seems it would fit between the Avenger and the Assasin, in reaction description. It's a solid 8.5 on my list.

TRACK EMB 2nd Review

Bowler style: Cranker (med spd, high rev)
Lane: 2nd shift league. Patchy backend, 35 ft single oiling
Drill: Pin directly above centre of ring and middle finger
       EMB (small logo) 3inch directly above pin.
       Long skid, medium arc backend

  This is my 2nd review of the EMB after we hit problems with the layout on my previous review.

  WIth this 2nd review and a new layout, I can say that the EMB is a great ball! The ball skidded way down the lane, cleared the heads and pines with ease and arced towards the pocket even when the lanes were drying up.

  Right out of the box condition, it skidded further down the lane than a polished eraser or a polished command zone. It kept its length and gave good backend reaction and it stores its energy really well. Will not flatten out as it hits the pins and it really hits the pins hard.

  Take some care when drilling it (layout) and you will find that it is indeed an AWESOME ball that will suit almost anyone. Even the heavy handed players will find it to be a great addition despite drying conditions.

  Buy it just to find out what all the fuss is about.
  Cheers,
  DLJ

Rate: 8.75/10

This is a second review because been use it for awhile
This ball is awesome for the last two set that I used I
shot 720 and 689 with two 260 plus games.

This ball seems when it hits the pocket it carries what feels
like 90 to 95 percent of the time. So I reallly like the ball
and hope Track kepts put out like this one.

Review No. 2 approx 80 games

Me: Lefty, 18mph ball speed, forward roll and low to medium revs

EMB drilled label, 0 finger/thumb weight and 5/8oz + side weight, 3" pin 10 c'clock beneath fingers, CG below grip mid line, 1" out from grip centre line, no balance hole. EMB logo is 1 1/2" above the grip mid line for arc reaction. Resurfaced back to box condition after approx 55 games.

Used this ball on 40 foot pattern (12 units to 7 board then up to abt 50 units on wood in box finish for 6 game set of 279, 269, 220, 279, 278, 279 for 1604/6 at Canberra Open on the weekend, playing 4 board at abt 28kph (abt 17 1/2mph) for a strong skid arc reaction, no over under on a shot that allowed 3 to 7 board.  It needs room and a backend to be most effective, but it will maximise your carry power and scoring potential if you are on your game.  If you are not quite on your game, go with something a little more forgiving but if you are hitting it well and consistently make it the first out of your bag!
