Getting heavy disc, no snap

[Parks]

I'm getting the feel of the heavy disc at the end of the throw, but I'm not getting the feeling of it rotating and ripping off of the index finger.

What can I try to get the proper things to happen from this point on?

Note that I've done tons of right pec drills trying to figure it out, so I need something to focus on or else its just reinforcing bad habits.

When you feel the disc get heavy, clamp down on your grip.

Feldy advocates a 70/30 grip pressure back of the hand/thumb lock. Bradley Walker clamps down with the thumb and further increases the necessary for disc pivot pinch strength by squeezing with both the middle finger and index finger. I've concentrated more on index finger strength building and clamping first but have gotten nice if similar results from the addition of tightening the middle finger as well at the end. On those few occasions I've succesfully tried it. My grip lock risk is higher with middle finger plus index pinching. That's why I haven't used it in rounds yet nor many times in field practice. My playing time sucks thanks to work and filming DG WAAAAHHHH! So little progress for me so far. And there's the stuff Feldy's clinic showed to be tried out as well when I get the time...
