FYI -- after a couple of nose slam-down landings at near stall speed (with extensive and expensive firewall damage), our landing procedure is a 60 kias half-flap approach with a relatively shallow and fully controlled touchdown at around 50 -55 kias. It makes little roll-out distance difference (this is not a STOL airplane) and keeps the insurance company happy. I wouldn't sweat the elevator trim business and would very strongly recommend not getting into that envelope.

Karl,
I would tend to agree that the 601 design probably has more flap than it needs. It might have been better with less flap, that would have reduced the pitch change (a good thing) and probably increased the max flap down speed (another good thing). The small increased runway used by 1/2 or 2/3 sized flaps would not be noticeable in a plane that by my standards can get into a postage stamp - this after flying a PA24-260.
