I went out to try out some new grip variations, because I have been unable to throw putters without flutter and my mids have been inconsistent lately. I decided I was going to throw just putters until I got them going straight with no flutter. Well, I think I finally "got" the power grip. I don't think I have my thumb completely forward.... but it's definitely at least half forward, and I was getting by far the best results that way. Putting my thumb pad directly above where my index finger is seems to massively increase the strength of my index finger's pressure against the inside rim of the disc.
It was amazing... my throw just felt totally different. I was throwing my putters with zero flutter into the wind consistently. My Rocs were like lasers. I wasn't getting much extra distance, but it felt so right and I was just so confident that I would get a clean release.
Then I switched to my drivers. Drivers that I had been throwing straight to slightly right before (169g and 171g DX Beasts) were now flipping into the ground. The 175g DX Beast I got for headwinds was ending up WAY right. The 166g DX Orc that I had been unable to throw straight was going way more straight (though it was still hard for me to control well... not sure why, maybe beacuse the rim is shaped very differently to what I'm used to).
BUT, my max D has not increased, despite the fact that I am throwing far way more consistently. This might have something to do with the fact that even with a little hyzer, my Beasts were not really coming out of their turn before hitting the ground. But, even the Orc which I was throwing kinda straight wasn't breaking any of my distance records.
I'm really really happy that I'm throwing my putters and mids consistently. But:
1) I'm questioning whether a 50% thumb forward grip is ok (it's like a hybrid between the "thumb forward" and "not thumb forward" picture in the "grip it to rip it article".
2) I'm not sure if I should be unable to throw a 175g DX Beast straight when I still can't really break 320-330', and a 166g DX Orc is giving me slight problems. Just seems wrong.
