I'm a 3 time a week bowler (210).basically go long,come hard at the end.Purchased a depth charge.My driller had it go long(only 2" pin)and come hard at the end.I only have used it once for a 690,but it may be the best ball i have ever used.Up to now it has been the DYNOTHANE SPECIAL FX.Not any more!!!!i think i will love this ball on my oily with nice back end house shot!!!i have only 2 perfect games and number 3 isn't far away.
