I follow your recommendations and understand that R19S-- is best option for upto 15 knots. What is recommended fin for 20 knots and above in choppy conditions?
You wrote:"But please notice that we are faster with a R 13 medium rake + 8 over 20 knots."
What about R19 M? I understand that there are 2 options to improve control in stronger winds:
1) Reduce rake (to e.g. 6+)
2) Go for stiffer fin.
What is better option in your opinion? Maybe just R19S (without --) is sufficient?
Thank you in advance
