I read some driving articles at discgolfreview.com to help get over the 350' hump. Long story short I was able to reach 400' on a few of my practice throws. It brought a tear to me eye to see a disc go that far out of my hand.

Has anyone else had similar experiences when learning to throw properly? (i.e. focusing on form rather than attacking the tee-box ferociously) I am having some trouble keeping the nose down now & I am turning over a lot of my throws.

I hear ya, I've found that the more I slow it down and take my time and be real zenlike, the further my drives go. When I forget to take my time (don't laugh, I forget all the time) and just try to gun it, it'll be an awful shot.
