My two pesos (are they worth more than the $AU now?):
WIIIDE arc through the turn, big as you can go, and actually power through a lot of the turn. Yes, I have actually fully planed out of a gybe twice and that's how I did it (then I blew my load and stuffed the rig flip). Plus I take note of how people do carve gybe and the wide arcs seem to be the basic ingredient.
That's about as neat as you'll get!
Note the wiiiide turn, the board is almost flat. You can use chop to surf through the turn.
