Back in the "old new ball thread" that disintegrated in some petty squabble, Roger mentioned that two Rotary Core balls were coming out. These balls should be winners for most bowlers. I throw both a Roto Grip Silver Steak SE hybrid and a Storm Hy-Road hybrid. Both are controllable OOB. The Storm has a softer coverstock, however the RG SSSE has quite a bit more backend reaction for me. I see another ball of the year award coming - LOL
For those who haven't seen the cores of these two balls they are similar but the Rotary core has the dense bulb further towards the outside of the ball opposite the flip block, while most Thunder cores have it near the center and closer to the flip block.
Most of the Rotary core balls were noted for (at the time) extreme entry angles and the ability to follow the shot inside.
