This is my first year with the Helix and I agree with the other post's, nice pull from the harness, will definately hand you a spanking on the odd occasion

. The reason I decieded on the Helix was because I was after something that was more challenging,without going all the way to the fuel's or simmilar.Basically I just ride freestyle,and I find that the helix is great fun.Depower is good but not complete,it can handle you riding towards it well,(learning to ride waves). Probably wouldn't recomend as a beginners kite. I have a 12, and ride 132 tt in 13 knots (80kg) and swap to my 9 at about 17 knots.No idea how far the 9 would go but at a guess high 20's.These figures are realistic and not from any brochure.Build is excellent, and have had no drama's at all. Hope tis helps
