I did one of these awhile ago, but have lost the link in the shuffle. I have gone through a number of form iterations. My most recent have focused on the release of the disc. I try and accelerate at the end of the movement and really feel the disc popping off the fingers. This has taken me from ~'300 to the ~350' foot range, but I seem to have topped out again. Any help would be appreciated!
