Thank's for the replys guys, I'm in SA, I've now done two 20km races in 3 weeks and we have another one coming up in April which is better. I don't really want a kite but my mate I sail with occasionally went on a Cobra with spin a few weeks ago and now wants one to play with. I have a local that wants to buy my 5.8 so I'm keen to upgrade so that we have two 5.8's and a 5.7 to race. Since you gave me the tuning tips Dazz I'm really enjoying the 5.8 and don't think I could change 2 up boats. There's not much weight saving on the newer ones is the mast just as heavy? I wouldn't mind if all the weight saving is in the mast.
regards
