Well I had this ball drilled a few days ago and I brought it out last night for the first time.  Of course I polished the heck out of it.  I was missing in my arsenal a dry ball.  I rolled this ball on completely burned heads.  The lanes were wood.  I bowled in a league that afternoon on fresh oil (with some other equipment) and I started playing 22 out to 12/13.  Well eight hours and another league later I was able to play that exact same shot with my Urethane Attack Zone.  I won four of the five pot games bowled that night ($790).  This was the main reason I was looking for this ball was to be successful in the late night pot games.  But I think this ball has found a permanent place in my bag.
