Deliverance LJ,
After 2-3 sorties that side stick feels the most natural way to fly; you think, you move. It truly makes you feel like you are the aircraft. You would have felt the same after a couple of trips, I'm sure of it.
I never felt otherwise with the center stick. It is a matter of practice and not one of a single passenger ride. Once you feel comfortable with everything it feels that way.
I think gums made some valid points. He flew both and should know, especially the value of the reclining seat for g tolerance. I never had problem with not being able to tolerate g the aircraft would allow, and often did not connect the Anti-G suit to prevent me from overstressing the aircraft. Body G- tolerance is a question of practice too.
