Rotory Cores
« on: October 22, 2005, 02:50:18 PM »
This is a question about bowlers matching up, or not matching up, to a specific type of core design. I pretty much only roll Roto-Grip balls. I love the Boom Cores and the Cyclotron Cores but for some reason the Rotory and modified Rotory Cores give me trouble. I know that must seem odd, with all the kudos given the Silver Streak Line, along with many other R-G balls using either the Rotary or modified Rotary Cores.

Has anyone else had similar experiences with the Rotary or modified Rotary Cores?

Thanks, Tom

What were the rotary core balls doing that you did not like?  What wrere the layouts on these balls?

Guys, thanks for the replies.  I was just curious as to other bowler’s results with rotory cores.

Rotomike, you asked about pin/CG placements? The Silver Streak was 4x2, pin below fingers on the centerline, CG kicked to the strong side 1-1/2” off centerline. The ball didn't seem to finish. Because of being a low track player hook set drillings usually work well for me. The Boom Cores and the Cyclotron Cores drilled similar and on the same conditions, produce excellent results.

Mark, you make an excellent point, some cores just do not match up to every bowler. Plus, with the new Roto-Grip designs arriving, I will always have options.

Thanks, Tom

I am a big fan of the Sonic series and never had great success with the Silver Streaks (Particle and Pearl). There were times when they rolled well for me, but over the course of a few years, they just never matched up well for me. I concer with Mark that the RS-1 was a great ball, but you really have to know when to use it and put it away.

 I'm sure if I had the opportunity to really tweak the covers and such, I could have found a happy medium with them. They are QUALITY balls, but they never really fit my style.
