I am 76 kilos, ride mainly in waves and sometimes in flat water. i use a 135 tt. I have the 10m 2010 xbow. Fantastic kite! Bomb proof construction, I haven't had any issues at all with construction and I have been flying this kite for past 3 months. FLIES INCREDIBLY WELL IN ALL CONDITIONS, love it. I don't have any connections to any shops or sales reps. Kite has a fantastic low end for a 10. I can ride comfortably (holding ground) in about 14-15 kn, and fly it comfortably (not overpowered) up to 25-28 kn. QR is awsome, works well. The only complaint I have is the top seal in the pump failed after about 2 months (white pump). I just replaced the top end cap from another old pump and it works well. Hope that helps.
