Im 6'3" and PA28's are just fine, i have flown almost all the variants, T67C slingsby and surprisingly the DA20 were both ok, you do sometimes clatter the stick on your knees.
One i was hugely surprised about was the new PA32, Shiny glass cockpit, roomy rear passenger area, i cant fly it because im too big. Well ok yes i could fly it but i couldnt get my heels on the floor so it was the choice of rudder OR Diff brakes. There was a stupid armrest built into the cabin which pushes my knee into the yoke and my head was always at a sideways angle. Very dissapointed.
