Bern,
When it's blowin dogs off chains and you just want to survive and its time to jibe the best bet is to keep the main sheeted tight and jibe through the smallest angle possible. That way the main is stalled and not generating power. Once the jibe is over and the kite powered up you can readjust the main.
If you jibe through a large angle your swimming.
Small angle with tight main and your right.
Seeing is believing.....

Most of my capsizes when flying the kite have been caused by the main. Especially when I pull the kite down. Such a big sail has just or in the process of being put away and I turn the boat through to much angle without adjusting the main and I'm gone. So the main is best on tight if you can keep the breese to the rear but once that angle widens get the bloddy thing off. Just when its blowin' and you don't much feel tike swimming.(not that there's anything wrong with swimming, but you'd want to be pretty good at it if you want to place).

Regards,
Phill
