Mike....in todays world of high torque and high speed servos I find that the servo speed is needed when flying 3D type airplanes. It isn't needed as much as the torque is and also the centering of the servo. especially at high speeds. By slowing down the servo speed just a tad to take the "edge" off of it the jet behaved much nicer and smoother. On my nose wheel I turned is down a bit more.
Many times you'll see a guy get into trouble because he'll start slapping the joysticks around and the servos are way faster than most of us and our reflexes.
I also dial in about 30% expo on all controls.
Each of us have our own likes and dislikes when it comes to setting up and airframe. For me by taking the edge of the servo speed helped tremendously. Especially in the landing flare.
