Roto Grip Ultra Sonic Bowling Ball

Another awesome product from Roto Grip Inc! Bought this in July and have loved it ever since. I had it polished up, because the stock cover was hooking way too much out of the box. It tamed right down and shot 645! very pleased with this ball! and have shot my highest 2 game block with it 544 (278, 266). Even though it is an awesome ball, carry down is the Ultra's enemy, when it gets too much. It loses its shnapp! Caution to those with a slow shot... this thing will hook big and i recommend it to tweeners and crankers only. You still need revs to get the full potential of this ball! Cheers, BJ

I was looking for a weaker resin ball that would give me an opportunity to play the drier outside line and shorter oil patterns. I decided to experiment with an axis-leverage drilling (2" from PAP with CG in the grip center for early roll and small arc) with advice from Jeff Lizzi. With the weaker ball dynamics, I originally wanted to go full leverage, but a 3 3/8" pin from PAP, according to Jeff, was perhaps a bit too strong for a tweener like me. This ball works best from the outside angle (first arrow); it has an early, but not-too-strong roll with a very smooth arc. However, with the above-specified drill pattern, the Ultra Sonic needs about 30' of dry backend to work effectively. I think this ball will suit well in tournament competition, say a third-shift when there is a significant breakdown in the oil pattern. In league play, the Ultra Sonic would be useful if there is a bone-dry track! Overall, I am pleased with this new investment!
