I've had mines for about 2 weeks now. Box finish this ball is very strong on a typical league shot. (The ball was dull when I receive it) First week the ball was hooking to much. Applied storm moon shine polish to it and the following week shot 722! It is definitely a keeper! Also the Complete Domination is a great ball also. I purchased both from bowlingball.com.
