ive had my 3.6 for over a year now and to be honest apart from the fact that the kite is dirty (i cant be bothered to wipe it down) every thing is as good as when i got it, the bag is rock solid even with all the extra gumph i lug around in it there's no fraying on the kite the line as new (i do use it, about 9hr a week) in fact the kite has improved with use, im sure that is turning faster and luffing less than when new ! and ive recently been hoisted skyward by it in 20+ gusts (no mean feat as im 15st) so all in all im well pleased with my budget buy, to the point that its taken me over a year to start craving something new, maybe a crossfire ??????????????
