Past weekend I was using the 12.5 Psycho in 18 knots, with gusts up to 22, and I had it in the water a few times. Both times face down. Both times, I still had my board snug on my feet.
Pulling the brake lines in, raises the kite, and flips it to one side. I did not pull on brake to move the kite to the edge of the window first, but raised the kite straight downwind. AS soon as it turns on to one side, I let go of the brake lines, grab the bar, and steer it up. Now comes the power, but it is no more than if my AB 8.4 would be doin the hindenberg, and then catch it just before hitting the water, relaunching it in the power zone.
To further specify, I made sure to keep my board on feet in front of me all the time, while launching it backwards, turning over, and then steering out through the power zone.
1. Board gives a good resistance to the pull of raising the kite backwards - which by the way is not much at all, but this does keep you very stable.
2. As soon as you can steer the kite up, it does give a nice burst of power, and with the board already in position, lifted me up, out of the water, and I was happily on my way again.
Important in stronger conditions will be to make sure that as soon as you flip the kite and can steer it out, to de-power fully, but I don't think this will be a problem, unless you are so over powered that you should not really be out there with such a big kite.
