To tack upwind I cleat the main, push the tiller, come in as the boat gets head to wind, uncleat, release a bit of mainsheet, throw the tiller around, hook on the trapeze and go out while sheeting to rebuild the speed.

Works for me. The only possible panic is when I can't unhook fast enough because something is tangled as I end up on the wrong side of the boat with a cleated main It's rare, but is a good adrenalin rush when it happen!

Downwind if I'm on the trapeze I do a two steps process. I first bear off and come in with the spi sheet in hand and then I jibe from the trampoline as I found that I need finer control on the tiller than I can do while running across.
