This ball has the characteristics of two of my favorite balls. It has the old black Roto Grip Silver Streak weight block, now being used on the Nomads. It also has an urethane shell that reminds me of my old blue hammer, but it can be polished. It's a little stronger than the Storm Natural to me.
I drilled mine 4x4 pin over the ring finger and cg a little right of the palm. No weight hole.
This is a great ball for lighter oil conditions and/or shorter oil patterns. It is also a great spare ball because it doesn't overreact. You can get right on top of the track, or the gutter on a Cheetah type pattern. The ball rolls smoothly and predictably. I was surprised at the carry. I consider myself a tweener and an old school stroker but I ripped quite a few racks with this ball.
Dry lanes , no problem, you now have a ball you can keep in play and grind it out with on the toughest conditions with much better hitting power than a plastic spare ball. A must for tournament bowlers arsenals.
