A lot of this is down to final approach technique. You should be able to let go of the stick/yoke and throttle(s) on final, and speed would not change (this means knowing which RPM/manifold pressure/throttle setting maintains the correct final approach airspeed/AOA), and the airplane is trimmed as to stay on a 3 degree glideslope by itself. If you did nothing else, the airplane would land firmly on the threshold at final approach airspeed/AOA on a 3 degree descent. Then, all you need to do is smoothly reduce to idle approaching the threshold, make a small, smooth roundout into the flare, and you’ll have a smooth touchdown using very little elevator. Elevator sensitivity won’t be an issue because you’ll hardly need it.
To practice this, slew out to a long final (300’ AGL/NM will put you on a 3 degree glideslope, so 3000’ AGL at 10NM, for instance). Figure out which RPM/manifold pressure/throttle setting keeps you exactly at final approach airspeed/AOA, and trim so that you can let go of the stick/yoke and throttle. Practice initially with no wind. It’s fun, and it makes landings easy, no matter how sensitive the elevator. It’s also very useful if you have to take your hands away for a frequency change, to flip a chart page, write down missed approach instructions, etc. The airplane will stay put on glideslope and on speed all by itself.
Now practice with different aircraft with varying winds, weights, and configurations, memorizing the power and trim settings. You’ll be nailing perfect landings in no time!
