I threw two sessions this past weekend totalling probably 3.5 hours. The distances I threw tell me a bit about what's wrong, but not so much WHY it's wrong.
Top 3 Long throws (airshot)
1 - 363' SL
2 - 362' TL
3 - 360' TL
What this says to me is that I'm not getting the nose down. Why is another question. I know I'm not hitting it particularly well. These shots were a max of maybe 15' high. If I tried to throw much higher than that, the nose up caused them to stall out and die at about 330'. It's quite frustrating knowing that I was throwing roughly 30-40' longer 6 months ago with more ease and accuracy and not knowing what changed since then.
