An interesting dynamic with stick forces.  I can't never remember which is
  which, but a thicker trailing edge provides the opposite of a thinner one.
  I just can't remember if thick is more forces or thinner is more forces...
  Ever looked at the Legacy's Rudder TE vs. it's Elevators.

Alan,

 

Maybe that was the attempt to lighten aileron forces (a failure) in the 300 series since the aileron trailing edge is 1/4 inch thick and squared off.  Oh, that's right, it does take quite a bit of force to reach that spec'ed 120 degrees/sec roll rate at 180 KIAS (note the SIZE of the aileron on the Legacy).  I can make a pitch change easily by merely pushing the PTT on the stick.  Accept it, it makes you a better pilot for when you jump back in a spam can!
