im back with a report. i bowler on my friday night team has the 715a. he is averaging 235. i asked him how he like the ball and this was his answer. this is a third game ball when the lanes dry up. he cant get the ball to hook in the first and second game. he has a very high rev rate. but he is using the 930t and loves that ball. so once again i have 6 bowlers who own this ball and they all say this ball will not hook like it is advertized. i used the storm vertual energy and shot 741. this ball was moving 7 boards harder than the 715a. can only use the 715a in the dry. 6 out of 6 people. 6 differnt styles of bowlers. same answers. extreme hook. maybe if you are bowling in the sahara desert.
