<BABBLE>i have the same stick as you i believe...the logitech extreme 3d pro.
as my stick has gotten older the problem has gotten a little worse the best fix i have for it is increasing the deadband on the Z axis aka the twist rudder so when I'm trying to get a lead on someone it wont notice the small rudder twists and also having a steady hands helps tons too.
I have also heard that twist rudder sticks aren't good for dogfighting because of this problem but Ive gotten used to it.
i took a screen shot of my z axis deadband settings but theres no attach button so i cant post it but i can tell you how i did it.
after my stick got broken in there is a little loose play on it, especially for the Z axis so when your adjusting it set it so when you jiggle the stick on the z axis slightly(not enough to run into any resistance you know, just the free play)the raw input you should see move slightly and turn the dead band up until the scaled input line doesn't move anymore when your twisting the Z axis within the free play zone.
hope you get what I'm trying to say
