Apparently we dont agree about what "waveriding" is.... (a lot more than which kites we like to use)
I agree fully with Eduardo, that if dead onshore it is not waveriding, but playing around on the waves - a very different thing, can be fun too, but got nothing to do with the term most think of when saying "riding waves" where you do the full bottom turn trying to get vertical of course, easier and much better the more sideshore it gets
If wind is just slightly to one side, and not dead onshore, things start to change hugely, and you can sometimes ride for quite long Down The Line, or at least get good cutbacks with the right gear and technique
I was referring to these conditions also, as I can not see dead onshore got anything to do with DTL riding, and the kite does not really matter here if not going around, IMO.
So maybe this now quite long thread is because we are, without really knowing, comparing completely different things ?
My intuitive assumption was that the original poster, Matteo V, was asking about which kites to use for riding in very onshore winds, but still riding all the way around for a cutback ?
Where you can NOT use "park and ride" like in side and side-offshore, but need a fast flying and turning kite that can be flown aggressively, and able to give you a good unrestricted course quite hard up onto the waveface after the bottom turn (meaning depower/forward flying is key), IMO and experience.
So I honestly think this thread is not only about personal likings and differences, but a lot more about how we all are talking about very different scenarios
