Not exactly what I was looking for...I probably didn't explain myself very well.
Each board Star-board sells has a recommended sail range and fin range. Does this mean that they would expect that, for the average sailor, one would probably want the smallest fin in the range for the smallest sail in the range, and the biggest fin in the range for the biggest sail?
Then, for a 57 kg sailor, should I reduce those fin size guesses by a few cm across the board? On top of it all, I'll be using weed fins, so I may have to make another size adjustment.
I don't have tons of $$$ to throw at fins. I want to make the most educated guesses as possible.
