Hello everyone, i am new to the site but have browsed and seen your good advice, i'm interested in a medium ball with good midlane hook for a bowler with slower to moderate ball speed, medium rotation, and good technique, i will use this as my primary ball in a league and school bowling, i'm looking for something durable that with good care can last a while and that has good hook but not outrageous thank you all if you reply

Im not really familiar with new Storm products but my teammate has one of these and he loves it. It is usually his first ball out of the bag. That is the Eraser Banshee.  Again Im not a storm expert so judging by what Ive seen from this ball and the way you are describing yourself and what you are looking for I think this would be a great ball.  Plus it has a great pricetag.  Im sure some storm guys could give you a better answer.

Roto Grip RS-X.  Strong reactive cover with good midlane read, but comes 1500 polished which will help a slower speed bowler retain energy.
