Got to the point where I was doing a few jumps yesterday off the top of some waves, got the timing right a few times and managed to land a few more than I had expected

However one thing I found was that no matter how hard I edged up the face of the wave I still flew downwind at such a high speed that when I did land, I could not retain an edge or even provide sufficient backfoot pressure to make any noticable difference to my speed (I'm 100kilos too

), I found that I could hold the kite up high and I would gradually... very gradually lose speed... but I was totally outof control of my direction (no edge) and would thus had to make sure I had massive clearance before any jumps.
What is the best movement to do with the board to slow down? I found carving a bit of an S helped a bit and at such a high speed was probably the most effective until I could just slam the edge hard in and kill some speed.
Is it possible to do that 'snowboard' style brake, where you point your board into the wind and pray that a big peice of chop doesn't fling you over... or is that only usefull at more moderate speeds?
Any other tips, particularly in reference to where to position the kite would be helpful keeping in mind that I usually kite in choppy conditions... Just looking for any tips

Thanks in advance
