Hi Slappysan,
don't worry it is more about handling. Biggest most typical error you also see people relaunching closed cell foils: Don't oversheet (pulling in backlines) too much for backwards relaunch. Otherwise the trailing edge will colapse as you see in the video. If you, by experience, find the right amount of pulling in the backlines just before trailing edge collapse (which can be hard for small cord as on small or high AR kites) and the kite starts to rise backwards, already in the first movement you have to release the tension a bit, otherwise the change of angle of attack due to backwards flight can cause a trailing edge colapse again....(as also seen in the video), all not so easy and especially not for small single skins, but it works. A more easy part of succesful relaunch is: Take your time and always control wind window position of kite which in most cases should be kept exactly downwind, so you have eventually even permanently move yourself, when the kite starts to drift to one side...
But as tomtom said, Peak will never be for water and light wind, even if it relaunches early (even in the water) and flighs in neraly nothing. So all 5-6 knts ridings I may test with the bigger peaks in the future, will just be to show that it is possible, but wont be fun at least not for me, looking for more than going straight, as I expect.
@tomtom
sorry if I try to answer the question for Armin,
but don't worry. Can't be a problem with V lines, changes could be that the middle becomes a bit more instable, and it becomes a bit more draggy but all in an amount that you never will be able to feel or measure the difference. I have flown my 15 m² Chrono which should be much more sensible to the high of the V with 12 - 27 m and the caused difference was even here very very small without correcting the bridle trimm. There are some kites as my sonic being a bit more sensible especially for shorter V, but the Peak can't be, especially not for longer V.
But even if the peak is designed to go downwind uphill, its upwind in a bit higher wind conditions is also ok to travel a bit around in flat land snow, here is the track I already wanted to show (and described) in the last post:
