R U serious this time or what? last time you didn't know whether to windsurf or kite. I'm not knocking you, because both are good.
Have you decided to kite? give the guy's your weight, size and wind you expect to go out in and they will help you. I know where there's some gear, but it might be to big for you.
I'm guessing if your 10 kgs either side of 70 then a 9m on a mid 130 board will be the suggestion from most the debate will be over the style. Personally I would suggest a bow kite but others will shoot me down for saying that.
Good luck my friend
