RE: reply my s-type 126 Q. please and win a free tip for your lovelife
I'm a bit lighter than you (68 Kgs) and have a ST126 for three years. Overall I find it an excellent medium/light wind board, but I would not put more than 8 sqm on it. You will have plenty of fun at 4 Bft, but 3 Bft is questionable. The C144 might be a better choice. I only heard bad comments about the ST137 so I can't recommend it.
