Absolutely the best ball I ever used. It reacts just like it's advertised. It goes clean through the heads and when it hits the break point, WOW what hooking power and recovery. Hits like a mac truck. The track is similar the the black widow sting. The difference is the recovery and angle. I am a full roller with a 215 average. First 2 nights in league I bowled 714 and 752. This was on a very long oil condition. I highly recommend this ball for low to medium rev bowlers. High rev bowlers might what to stay away from this one. It will be hard to control. Great job Hammer.
