Let’s just say that 99% of us aren’t Jesper Svensen, Osku or Belmo. I don’t have a 600 rev rate and throw the ball 20 MPH. And i can’t split half boards on the lanes like those guys. So, I use urethane when the lanes have very little volume or very short oil or a combination of both. I’m not a urethane hater. I have bowled a few 800’s and 300’s with urethane (and polyester) but I know my limitations. The truth is, this ball rolls like urethane but finishes on the backend like a reactive ball. For me, it’s kind of like a Pro Motion that had a little baby. It’s cleaner up front, silky smooth on the backend and enables me to play in the high friction areas of the lane without any over-reaction. I did a pin up 4.5†pin to PAP and a 2.5†pin buffer layout on this one to keep it fairly strong but not defeat the purpose of the ball. The Capacitor Core has a high enough RG and low Differential to keep the ball from flaring too much. The Rev Controll solid coverstock keeps the ball from rolling too early but allows it to have more recovery downlane than a typical pure urethane cover. It fits between the Pitch Black and a lower end reactive like a Tropical Storm. So, cleaner than the Pitch Black and smoother on the back than a reactive. Use it on blitzed lanes, screaming backends and anytime you need to keep your angles closed. I drilled one of these for my girlfriend who is rev challenged and has very slow ball speed (12MPH). She bowled a 220 game with it first game! Hope she doesn’t read this. But, that being said, this ball is a great option for bowlers in a similar situation. #Stormnation
