The New Roto-Grip Silver Streak Pearl, or should we say "Purple Streak" is the best of the "Rotary Core" balls to date! We loved the "Silver Streak" for those medium to dry lane conditions but the New Pearl is much better!
We label leverage our test ball with the pin at about 1:30 and the CG in the strong position with no balance hole. We found this ball to be at its best just after the first game of typical league play when you start to experience the track area of the lane drying up! Our ball floated threw the heads and made a very strong hook on the backend. This IS NOT a skid/snap ball! but more of a Strong Arching Hook style of ball. Those of you who have stronger releases will get more out of this ball than those of us who don't.
The coverstock is "Fully Adjustable" but you will want to maintain the out of box finish for the best performance overall.
The Hitting Power of this ball is excellent! No Problem here!
If you want a friendly ball with great hitting power, then this ball is for you!
We will Highly recommend this ball to all bowlers!

drilled pin over the bridge
cg kicked out a little
no weight hole
condition fresh med house shot (top hat)
squeaky clean back ends
lined up at 22 played 15 to 6 at the break point
this ball has great push and a strong arc back to the hole
hits hard and leaves few corner pins
very forgiving if you get it wide
every so slightly over/under with clean backends 2 or 3 frames of carrydown smoothed it out though
over all a great ball for a great price
not much experience with storm/roto-grip
mostly a brunswick/columbia guy
But I really like this ball

This ball gets down the lane, makes an excellent turn and then watch it hit. I thought Storm balls hit hard - this one hits harder. This is the first Roto Ball I have had, and I am sure it will not be the last.
If you are looking for something to look pretty down the lane and score well with - this is the ball for you. WOW!

Finally a ball which can compete with the Ti messenger Pearl!!
Drilled mine 5 x 4. The ball is extremely clean through the fronts but watch out as the power gets applied. Very strong and consistent recovery. Strong hitting ball. Sucks the corners off of the deck.
Great ball to play a bank shot.
Did I mention the ball looks great too.

I shot 300 with it tonight, with very difficult lane conditions. I was using my Storm Boost, and it just wouldn't react right - I switched to the Silver Streak, and never missed - 19 strikes in a row, with broken up heads and carry down on the backends. Even with fresh lanes, this ball still works good. For a low end resin ball, this one is exceptional.
If you are looking to experiment with something, without paying a lot, TRY THIS BALL!!!!

New specs: 15 lb., pin about 1 ½†below my ring finger with the CG kicked out quite a bit. I had a weight hole drilled in it to bring the side weight back to 0. WOW!! What a difference. This ball makes me look like I have a gorilla hand. It revs up very quickly, and continues to rev up through the pins. Since I have redrilled it, I have had to pull my spare ball out only once. This ball cured my 10 pin problem. This is a great, great ball. I wish I would have drilled it like this originally, I may be averaging 235+.
Post by: dreamer_51 on April 04, 2003, 03:07:09 AM
On the right condition I would rate this ball a 10.
Post by: Can you Rev on May 20, 2003, 12:05:48 AM
I got exactly what I was looking for. On longer oil patterns with decent volume the ball starts revving quite early but doesn't grab very early. After clearing the midlane it is revving very hard. Once it does hit the dry boards it is not long until you see a very strong move to the left. When the ball gets to the pocket there is nothing left on the deck. Light hits blow pins everywhere, flush hits generally have messengers flying. If it comes in high I'll leave a 9 pin pretty much every time.
This ball truly is a beast of a ball if you have any hand at all. Especially on the backends. I can't imagine why anyone would need one of these balls leverage drilled. That would be an unusable amount of backend it seems. But some of you all do probably throw some pretty weak fluff, so you might be ok 3 3/8 x 3 3/8.
Anyhow, all around this is a great ball. It does well on a variety of patterns from 38-43 feet as long as there is head oil and not much/if any carrydown. I haven't tried it much on carrydown, so at this point I'm not going to judge how well it will or will not handle such conditions.
Hit and carry of this ball is simply devastating. I'm quite convinced that just about anyone who sees a variety of patterns would be very happy with this ball from Roto Grip if they were to give one a try.
I've got the solid too....will post a review on it later when I actually find enough oil for that monster.

Ball was drilled pin (3") slightly above and right of ring finger, and cg is kicked right of that approximately 3/4". There is a small balance hole.
I have med speed and above average revs per my drillers, and track approx 1" from fingers and 1/2" from thumb.
Now on to the ball's performance:
I have now used this on many different patterns, and 2 different oils (Offense & Legends). Although the patterns were basically THS, they had been experimenting with new ones, and the oils. I also was able to play some on some modified sport shots as well.
This ball seems to always be clean through the heads, even with light oil. But beware, you do need some oil, and to some decent length. Once this ball reads the dry and decides to move, it MOVES HARD.
I have been able to easily adjust with slight change of lines or slight hand/wrist adjustments, and the SSP responds accordingly.
It may or may not be a 1st out ball depending on your lanes and likes, but it definitely is one to have in your arsenal.
BTW...despite playing 95% on wood lanes, and with well over 50 games on it, I have not seen any loss of performance, and no major wear/tracking.

Pin 3" from PAP
CG in grip
I bought this ball yesterday and threw it for the first time the same night first shift league. It took me 4 frames to figure it out and then it was AWESOME! I threw a strike the next 15 of 16 frames. The ball is a flat out MONSTER. Great hitting power with nice backend finish. HIGHLY RECOMMENDED especially for the price.
Post by: drillbit on January 23, 2004, 04:12:18 PM
Lane conditions vary from a THS to a dryer tournament shot(no puddle in the middle), to late-shift carrydown with drying heads.
At first, this ball was too strong at the break and would burn up before the pocket, but after about 20 games or so it calmed down a bit, and became much more usable.
This ball clears the heads on all shots I've bowled on it with. It then reads the midlane very well, and makes a very strong move on the backend. If there's some carrydown, it lays off or even quits if theres a lot of carrydown. When it hits the pins, it keeps the pins very low, and mixes very well, for me at least.
All in all, I'd rate this 9/10. Good job Roto!

I usually like longer pins and high top weight, but oh well.
Drilled this ball up aggressive, probably too aggressive. You get what you ask for. Pin right next to my ring finger, cg kicked out about 45 degrees, basically a 10:30 drill (righty). I probably should have stacked it instead. On our league shot, this ball goes very long but it expends too much energy too fast due to the drilling. So now it is more of a conditional ball. I take this out when there is a lot more oil than the out normal league shot (medium/medium). When I have to play 10 or outside of 10, this ball takes over. It goes about 40 feet before it even thinks about hooking and then it starts it's path to destruction. Ball carries very well on this shot. Due to all the oil and being a pearlized ball, it will leave a 10 pin if you start pushing it or put too much speed. I can also use this deeper on the lane if there is a heavier concentration of oil, but could not play a big hook with this ball.
After playing around with releases, I realized that if I put more spin (lower the track) on the ball, you can definitely play a bigger hook. But not too much, or it will die before it reaches the pocket. But that is the drilling, not the ball.
Overall this ball is a good ball (especially for the price). It is definitely a go long and snap ball, but do not drill too agressive, unless you like playing a hook and set shot. Definitely recommend.

All I want is to carry.....when I find the pocket
Post by: Rdrvgs1 on April 23, 2004, 11:00:57 AM
16.10 total weight
3.4 top
3.5 pin out
I drilled the ball 3.5 X 5
the ball snapped when I first drilled it, but after abotu 50 games it has an arc to it... a very strong arc, the more I use it the more predictible it becomes, it hits hard and no over/under. Used mostly on a second shift with carry-down.

Profile: 15 mph, medium high revs (approx. 300 rpm), minimal axis tilt (30 degrees guessing)-- basically a power stroker / tweener.
I've had this ball now for a couple of months and have tried it on two different synthetic patterns. I bowl league on both.
In one word: unholy. Warning: take the specifications that Rotogrip lists for this ball on their website seriously. Roto is dead on with this one. I wish they'd list a breakpoint shape like Brunswick does since this may have dissuaded me from purchasing this ball.
Skid flip for me. Archetypical pearl resin reaction. One look at the very sharp and angular core should give you an idea of what this thing is all about. This is a high performance ball masquarading as a midprice ball. There's nothing middle about it. Of course that's good and bad depending on the lane condition. The backend is very angular and practically never quits and this is also the hardest hitting ball I own. I imagine a sport or tourney pattern would tame it down but I bowl strictly on league lane conditions.
Condition A: 35-40' synthetic, medium heavy x'mas tree pattern (40 units in the middle) with a generous buff out region
Condition B: 40' synthetic, light oil (18 units in middle stepping down in 5-board increments to 3 units outside 5), squared off backend (no buff out)
On condition A: Excellent reaction due to the strong heads and buff out region at the rear of the oil line. I can swing it out from 12-15 and it has radar. Admittedly this is a very forgiving and high-scoring pattern but it does break down fast, probably because people like to throw aggressive stuff on it. Even though this is a pearl it sometimes struggles get cleanly through the midlane after a game or two of five-man league. It isn't fazed by carry down, though.
On condition B: um, er, unholy. Not necessarily unholy bad but the combination of lighter oil and flying backends means I have to be very consistent with ball speed and release because I'm throwing out to a breakpoint and it zips back like a raving lunatic. I can tear it up on this pattern bowling practice but things get iffy fast in a five-man league environment where oil lines are crossing and breakdown is happening at an accelerated rate. I don't use this ball in this league anymore for this reason. Lots of splits and over/under. But it hits EVEN HARDER on this pattern due to the intense backend and entry angle. Perhaps with more practice ...
Comparisons:
1. Black Danger Zone reissue (4.5x4.5, pin at 1:30 above ring): my BDZ is drilled identically to the SS pearl so it's a perfect comparison. The BDZ gets similar length (40-45') but it's more forgiving -- more rolling and hard arc than skid flip. It has ~5 boards less backend than the SS pearl as well on the same line and lane condition.
2. Monster Slay/R (4.75x4.75, pin at 12:00 above ring): Brunswick claims this ball has 90/100 (highly angular) breakpoint shape. Well, that would mean the SS Pearl would be about 180/100 on this angularity scale. No kidding. The Slay/R is actually a rolly, smooth ball compared to Mr. Unholy, I mean SS Pearl. The SS pearl also has about 10, maybe even 15 boards more backend than the Slay/R but also turns the corner 3-5' sooner (perhaps due to the slightly stronger drilling since Rg and diff are pretty similar between the two).
Overall I really like this ball and it has a definite place in my arsenal but I'd like to see this core around a weaker pearl cover for my game. Any ball that hits this hard as has such a strong reaction has a place in my arsenal. But, my release seems to promote a hard arc or angular ball reaction, admittedly. I would guess the SS Pearl would work best for strokers, though crankers might also love it per their typical higher ball speed than me. Just make sure there's decent head oil. I would also recommend drilling it 'weaker' (or at least 'forgiving') as far as Pin-->PAP and MB position for typical league conditions to maximize it's applicability.

I've gone back to playing more down-and-in lately (my preferred game, really) and the Silver Streak Pearl really shines now. I would guess my rev rate is around 250 rpm when I'm stroking the ball and my ball speed is 16 mph at the pins. My previous review was based on my tweener/power stroker release.
Whereas before when I was tweening the ball I found it very condition-specific given the sharp backend, now it's useful almost on anything. It gives a very precise, angular read and by stroking is much more forgiving of minor speed and release variations. Tweening the ball I found it difficult to control on flying backends unless I was near perfect with my mechanics (but when I'd get lined up and in a rhythm, look out).
Also, as I said in my previous review, it is a very strong pearl and this, in concert with the angular read, means it also handles carry-down well. I've tried it on three different patterns ranging from the light to the heavy end of medium 40' and it's great on all three stroking the ball.
If you're a stroker I think you'd really like this ball on a wide variety of patterns between the extremes (toast light and soup) since it provides good angularity for entry angle and a strong hit. Being a pearl it's also clean through the heads up to the point where practically everything stronger than plastic or polished urethane is checking up early. It hits and carries just as well or better than my black danger zone reissue (drilled identically and in stock compound finish) either stroking or tweening the ball and is about 5 boards stronger but with nearly identical length.
It's too bad Roto discontinued this one for the RS1. This one's a sleeper and I see why it's been in their lineup for so long and garnered so many honor scores. I see the RS1 as a lot stronger and thus more limited in it's applicability (especially since they already have the Apocalypse in their line up and my pro shop driller really likes his Apocalypse). Personally I think my purchase of the SSP a few months ago inspired his getting an Apocalypse since he'd never seen a Roto thrown prior to ordering mine. He would have probably gotten a SSP as well but his house is the one with the heavy medium 40' oil I mentioned above. That alone says a lot since he's drilled a whole lot of balls for himself.

I recently bought a used one, it is 15 lb, a drop for me, from my usual 16. Old age creeping in maybe?
This ball is laid out with the pin under the ring finger with the cg swung just off the palm. A small hole is drilled in the side to give it 5/8 ounce of side weight. (Not sure of the exact measurements)
THIS BALL IS A BACK END MONSTER.
The shot it has been thrown on, is THS, oiled to about 25 feet and then buffed to 40. The backends are usually clean, but there is a typical carry down phase that usually makes the ball check up in the second game. Most often the third game, things really start to fly.
Nine games into use and I am amazed at the versatility of the ball. It handles oil surprisingly well for a pearl, as I can get left with into oil and still feel like it is not skidding too much. It has allowed me to swing the ball out and get an angle to the pocket that I have not had in years. The hit and carry are phenomenal. Off hits, high or light, have pins scattering all over the deck and on solid pocket hits it destroys them. I have left a few ten pins with it, primarily on balls I tugged.
Series so far with it 743 - 633 - 717. Very happy with the results. I would suggest if you are looking for a pearl ball, keep this one in mind. I believe it is discontinued, but I have seen pro-shops with them. This ball is suppoosd to be tamer than the new Roto-Grip RS-1, but I sure as hell do not need more than the Siver Streak Pearl.
Thanks for reading;
Fabes
