Many thanks Remi for your answer, it's very helpful for me
I have another question, from another thread
I very need your advice about fins. I'm rather heavy (110 kg, on spring I hope 100), 190 cm. I'm going to order 2 fins Select S11 Race. I intend to cover three slalom sails 7.8-8.2 (now I haven't any this size) and 9.5 + 10.7-11. Which size of fins would be the best? My prediction is couple 57 and 61 cm long.
Am I right? And second question: whether fins for iS150 and US147 should have the same size?
I would be very grateful for your answer, Remi.
