I'm a SL66 user & lover. The front tilt is wonderful. The lens also racks out on a bellows so that you can get very close (6 inches, I think)with the standard 80mm lens -- and if that's not close enough, you can reverse mount the lens to get even closer.

It's big, it's heavy, and it's true that you have to change hands to focus & wind, but you get used to it -- wouldn't trade mine for anything in the world.
