I noted one thing, when launching a Peak4 in 5 m2 in higher winds - and would hear if others have experienced this, or it was a "one off" single incident:
Wind was for 6-7 m2 tubekites on waveboards (not foilboard), and I put my 5 m2 Peak up dead downwind, in extremely gusty wind because of wind shadows (otherwise I wouldnt have dared to hot launch in this wind)
It flew and was easy controllable, but both tips where curled in.
Like the hard wind has shut the air intakes to both tips inflation points - I dont know...
I thought I had kinks on the bridles and was about to land it after some time - but then the tips opened.
From then on no problems the next hours when out - I disliked how it flapped like crazy when fully depowered in this high wind and you walk out and in from the waves, feels wrong and must be aging the kite fast?
But apart from that, even when walking out behind wind power stations so wind could not be any gustier - it worked great.
Did not fold or drop or do any odd things, even in this horror wind.
Out in the surf, on a "normal" waveboard, upwind was just fine, and riding the waves DTL was a great experience - it was so fast and nimble and easy to fly onehanded, and could drift, so I could ride a lot higher on the waveface when doing bottom turns and cutbacks, meaning the bottom turn even on small waves, was high on the waveface as it should be
