Bowling balls are like infections. When one bowler gets one and likes it, others around them start getting it as well.
The RAW Hammer Solid was like that for our circle of bowlers. Saw my first live 300 thrown with one. So I bought one. Which made my girlfriend buy one and so on and so on.
Haven't seen any noticeable issues on mine. But love the RAW Hammer. Definitely the King of low end balls in my experience.
