The roto grip wrecker bowling ball is a very good bowling ball from rotogrip. I made a mistake was giving my wrecker bowling ball to my brother. When I had the wrecker I was killing the pocket all the time. I use this bowling ball on medium to dry lanes and the ball was just to good. That’s why this ball is still on sale for this long. If you ever get a chance to get this bowling ball we should. I the highest set I shot with this ball was 756 which is pretty good.
