This was my very first storm, and i was very impressed with it and it ended up being my favorite ball. unfortantly it was a 14 pound and the next season i ended up haveing to switch to 16 units to get me to slow down. when i use to throw the ball alot slower it would start its role about mid lane our so then when it hit dry it would explode and fly into the pocket. but for being a 14 and me being a stroker at the time i didnt get great pin reaction sometimes leaving a lone pin like the freakin annoying 10 pin, but sometimes it was just coming in at a bad angle
