Update fins for an outdated (but still valid) Formula 161
*** For ALL ***
I (finally) would change my old 70 cm Deboichet R13 S+ fin (old grey series) with a more updated formula fin for my F 161.
Despite everything, R13 is still a good FAST all round fin but, racing against newer fins, its limitations are evident especially in upwind angle.
I have seen a lot of brands have specialized in making very soft fins because of improving just upwind angle; so what fin do you suggest for:
board: (2007) Formula 161
sail: (2009) Gaastra Vapor 11 m
sailor weigh: 85 kg
wind condition: light to medium
Thank you in advance for any help.
