Is it the ball or me but since I had my Venom Strike drilled up (50x5x40) my series has been great. A 659, 656, and 657 series for the past three weeks. I had been struggling this year so I thought I needed a ball just a little weaker than my Raptor Attack. So the Venom Strike seemed like the ball and I would have to say it is. I like the Motiv equipment. It fits my style very well.
