Default Definition(s) of pitch sensitivity? All-flying tails

I agree with Kirk that the 2-32 feels pleasant due to the anti-servo
tab. I remember it was the same with the single place Lark.

I'm sure that part of the "problem" with all-flying tails is that the
mass in the system, which is higher than you would expect due to the
need for mass balancing, imparts a little more momentum to the control
system. If you correct one way or the other the surface will keep
moving a little after you stop the input. I suppose we automatically
learn to stop the input with different timing or physically stop the
stick from overshooting the desired displacement. You basically
have to stop the control from overshooting, whether you realize it or
not, which I've never noticed with normal elevators or rudder-vators,
mass balanced or not..

Again as Kirk suggested, this was most noticeable in an old, light
glider that suddenly was an unpleasant handful when we flew through
wake turbulence on the takeoff roll.
