BERN, have you spent any time in the Training arena? Morphine is real good at watching what your doing and explaining what he thinks you might be doing wrong. I don't know how good he is with stick setup, but I know he can spot you over controlling your plane and such. It might not be your stick, but how your using it.
As you know there are a million ways to set your stick. When I came over from AWIII years ago we all flew relaxed realism. That means no matter how hard you yanked on the stick you could NOT black out or go into a spin. This means when I started flying here I was sooooo heavy on my stick I was blacked, stalling, spinning and every other thing you could think of except flying! I had to learn to fly all over. Back then I did add some damping to my stick because it took half a second for me to yell at myself "easy stupid!"
So the damping helped me not over control so quick. The point is I had to concentrate very hard on NOT holding the stick like I was hanging from it off a cliff and NOT to yank it like I was trying to start my lawn mower.
Smooth and easy is the ticket. The side benefit is that once you start getting the hang of it you also burn less "E" and that is ALWAYS a good thing in a fight. So maybe you should just set the stick at default (after all somebody set it as default for a reason so it can't be all that bad) and learn to go easy on the stick. Have one of the trainers watch you fly and they can give you some pointers. An hour with Morphine is better than 40 in the Mains for learning how to fly and fight. Give it a go, I don't think it could make you an worst right
