I threw a buddies 750 M4 and it would pop up and turn with little to no fade into a slight headwind. It was very different/understable from my proto 400 M4 that flew like a well seasoned Z Buzzz, dead straight little to no fade. Of course, I didn't season my proto 400 M4 so maybe its supposed to be an understable turnover once it beats in. My point being that they seem to have started off more stable and become a much different disc... I know very small sample size YMMV.
