Field Camera (lightweight) with two odd needs

I think with some fussing around it wouldn't be to hard to load a hassleblad one-handed.

Rollei 600x or SLX since it has power wind to the first frame and power take up after the last frame and the inserts are loaded in a straight line path. No rollers or clips to thread film around or under. Inserts just drop in to the opened back and no need to move the empty spool when re-loading. So one hand loading is easy.
