Hi there I'm 15 years old and I've only been windsurfing since the summer so you could imagine that I have quite a few questions. I was wondering if the investment in formula is worth while for a bay like mine and a sailor like me. I also only just started planing through my jibes a few weeks ago so would formula be too much for me to handle? It usually blows 17kt or so during spring and summer but during the fall and winter it is quite light (8-12 or so) with the occasional 30kt front comes through. It is also quite choppy most of the time here. I already have a 76 wide slalom board and an 8.5 and a 9.5 which is a bit too big for the board that I use on the light days which are sadly, now becoming the windy days. Would formula work well in the conditions that my slalom board doesn't ie. 6-11 kts? Or should I just get a bigger fin and use my 9.5 on my 76? I already have a 265cm boom and a 520 mast would those fit on a sail that works in the single digit wind speeds? My weight is 65 kilos. Anything is helpful thank you!
