Here's what I do...

Just before I think it's time for me to start snuffing, I fall off just a bit, ease the traveler and the main, set the tiller on the boat(over the side), do the kneeling thing that I was talking about, put you foot on the tiller, pop the cleat, and then start snuffing. By the time you get to the mark, you should be almost done snuffing. If that's the case, you can use your foot on the tiller to start rounding up. Again, thats only doable if you have enough sheet and traveler out, cause if you have it sheeted too much and you start rounding, OVER you go.

It sounds complicated, but it's doable. You have to be creative on the third hand.
