All this ball charts about Roto Grip made me pull out my old Roto Grip Blue pearl and test it against the Silver Streak pearl, Threat, Cherry Bomb, Smash/R and the Lane 1 XL. All bowling balls were drilled similar but not the same.
The lane conditions were wood, morning senior oil about 12 hours old and one senior league already done. So the outsides were very dry shorter oil and the back ends very strong. I should have bought the Sonic X also, it usually works well on this condition.
The Threat handled this condition best for me standing 32 swinging through 17 to about 8 and back. Not flippy, but strong and carried very well.
Silver Streak Pearl, I had to move one board left to 33 playing around 17/18 out to 8 and back. Stronger backend movement then the Threat, but that was extected.
Then I tried the Blue pearl. Both the Threat and SSP were in box condition, but several months ago, I took some polish off the Blue pearl to give me a better read. Had to move three boards right, plat 15/16 out to 8 (the break point I was playing) and the ball read the lane very well and arced to the pocket with great control, but still strong, not as strong as the other two, but that was expected since it wasn't polished. But the ball ws strong, had great carry.
Smash/R seemd to roll out with these conditions. There was no comparison. Smash/R hit flat unless I really kept the speed up.
Cherry Bomb, Just too much ball. never quit but very hard to keep right of the head pin.
Lane 1 XL, The dry lanes gave the XL all the help it needed. I could move a litle further right, not have to swing the ball near as much and it saved enmough energy to carry the pocket.
All in all, I think the Threat and the SSP wsa the better ball (of the ones I had with me) for this condition. The SSP has plenty of core/weightblock power to carry the pocket.
This was just my observation without looking at ball charts. Who cares about ball charts, they are just advertisement gimmicks.
