I'm 78kg and 183cm. Been off the water for a couple of years after I tweaked my good knee (ie two suss knees now

). I like the look of the Haze cos it has plenty of flex - that's got to be good for dodgy knees, right? Question is what size should I get? I'll be riding mostly in small surf, 15-20 knots is the average wind on a good day. My kite will be a 12m Naish Cult.
