My daughter had similar experiences with the Rocketechs. She is by no means a power hitter, 5' 4" 120 lbs dripping wet and a lefty slapper to boot. She was going through 3 Rocketechs a year until I finally got fed up and tried something else. She loved the bat, but I got tired of them getting flat spots and splitting open. She had one that literally was a triangle.
