See you asked this a week ago, have you since tried the regular semi suicide mode?

Hooking to the loop makes it alot quicker to relaunch if you do drop it among the waves, they don't have to be that big either to roll the kite.
There's a big throw on these bars too if you push the stopper right up. I've never had a problem with the kite staying powered up after crashing. Just remember to attach your lines to the appropriate knots so you don't have to pull a heap of depower to unhook comfortably (or you'll lose some of that throw).
I found it's a skill in itself after crashing to save the kite before it slams. Pulling in the leash & holding the loop with one hand while steering the kite to 12 with the other before hooking back in. I'm an amateur at this & still figuring that bit out.
Feels safer in semi suicide mode too, you can still release & flag the kite which you can't do when leashed to your depower. Less chance of losing the detachable LF chicken loop too

Hope you figure it out mate, it's such a rad feeling having the whole power of the kite through your arms.
