Here's a picture of Ghosth's stick setup....

The sliders, going from left to right represent your stick movement, or your input.
The sliders from bottom to top represent the control input to the plane in the game.
So in this picture you can see that Ghosth has his setup so that the first quarter/third of his "yank" on the stick dose little in changing the control surfaces to his plane, but as he moves the stick farther thru his "yank" he gets more/quicker response of his planes controls.
So to get rid of "nose bounce" you want to have the first few sliders low and not change much between steps... depending on how heavy handed you are with your stick. When I came over from Air Warrior I flew mostly in the "relaxed" realism arenas so was use to really yanking on the stick. I have since learn to be very easy and smooth on the stick over the years. Most of my sliders are at the top. My rudders are the only ones I still scale and even those the "0" slider is 2/3 the way up slopping to the top from there.
Only you know how hard you yank on the stick, so only you can adjust it. Starting with someone else setup, like Ghosth's here can help when trying to understand what your trying to do.
Good luck, and welcome to AH !
