At a Bonanza proficiency course I attended a few years ago, a well respected guest instructor from the States (and experienced others)advocated landing with the gear DOWN to dissipate energy.
Beachie, I reckon that's crap!
How many people get hurt doing belly landings?
The only one I can think of is a guy in Fiji many years ago who stopped feathered the props on an Aztruck and tried to get them horizontal. Didnt get it right - Aztruck on its back, cabin crushed, pilot dead!

PS: That's why I steer clear of Bonanza proficiency courses!
