I noticed that what Beato said earlier about the Non-throwing shoulder coming through too early was one of my main problems. I fixed it before, but wasn't exactly sure what I fixed, then I started suffering from it again, and finally realized the disc hit my chest a few times and I was throwing my non-throwing shoulder forward too soon.
Also, I noticed that my run up has slowed down dramatically compared to what I'd been doing before when I was OATing disc out the wazoo. I can throw Roc's 350' now with just a simple slow run up, but it's weird because throwing max distance feels different, and I can't quite nail it down now. My final step feels way too long, but trying to fix it doesn't seem to work, or help my distance. I can throw smaller diameter disc much better now in the 350+ region. Where I could easily throw my Wraith's and Nukes well into 380-410 range. Now I'm struggling to do so, I know it's because I've changed my form some. But, this is helping me some!
Eventually I hope we'll both catch on to those little things we've both missing and start exploding well into the 400+ range. Cause, at this point it seems like those little details are what are holding us back!
I've felt it coming, and days where I can hit 430' effortlessly. But, those days are few and far between. One day I'll be able to claim 450'+!
