First off have to say great looking ball smells good rolls amazing.Really like the colour choices on this ball love bowling balls with crazy colour combo in them makes them look amazing down lane.Storm has made probably one of the most backend asemetrical bowling balls out there.If you need backend this is the ball to drill for sure.Clean threw the fronts and tons of backend recovery no problem for this ball lol.I like to use this ball more on the break down little bit of carry down pump left and will it.Not something i would use on fresh for me other bowlers who like the down and in game maybe if used on fresh hit surface with 2000 pad just to control the backend a little and not get to muc over under,i give this ball a 9 out of 10 for sure.Drilled mine 60x5x35. bowlers out there you need backend and lots of it drill the snap lock you wont regret it trust me.
