If they are pedaling the uphill side, I suspect fatso will get dropped like a hot potato, assuming comparable fitness levels.
Correct on both counts. If they're coasting the heavier guy goes further before he stops (because he has greater momentum at the bottom). If they're pedaling he gets dropped, and not just because he's out of shape -- even if he's a lean muscular dude, he's got more weight to carry up the hill.
