Thread starter again:
Thanks for your reply Mark. Highly appreciated.
However, I feel that changing from 48cm Ready to Race 48cm R2R Downwind will be a too small change. However, I have no experience with the Downwind fin, so you might very well be right.
My thought is as follows:
50cm fin with 9,3
48cm fin with 9,3 when overpowered
48cm fin with 7,9 when powered
46cm fin with 7,9 when overpowered (R2R or R2R Downwind)
I've read in the Team Forum that the bigger Isonics (at least the 137) need a more powerful fin than the Downwind fin to provide upwind performance. Will that apply to the 127 also ? Even in overpowered conditions ?
