I think I'm the odd one here... Drilled one up this past weekend and threw it for the first time tonight in league. Couldn't seem to get out of the thumb hole. Hung up quite a few shots...Threw a decent shot, then would hang and yank it an arrow left. Stuck with it through the first game and a half, then had to make a switch back to my regular layout to prevent tanking the entire night.
I'm going to give it a little more time (will throw a few practice games this coming weekend), but so far it's not quite there for me. On a side note, the few shots that did manage to come off clean, did feel good.
