Recommended them to a couple friends, and also drilled one up myself so we had several of them rolling down the lanes last night. This ball HOOKS, I had to put mine away, but my friends were able to throw theirs. I went 70x4.5x35 with mine, went 75x5x40 with the one for the guy that bowls with me. He's got an extra 50 revs on me, but 1-2 mph too, so he was able to get deep and wheel on it. Exactly what I was hoping for reaction-wise for all of us. We have Nationals coming up, thought it would be good on the team shot, then we have a tournament the next weekend, followed by a lot of sport patterns all summer. Doesn't look like I'll be able to use this one in league much, but that's ok, wasn't the intent anyway. Motiv makes it really easy to drill and recommend stuff with confidence, you know every piece is going to be excellent.
