Sergio, what are some of the 'softer' weed fins you know of?[/QUOTE]
Lanee, I was not referring to weed fins in the reference to 'soft' fin, I generally don't like weed fins, not sure if soft would not apply to them, the only ones that works relatively well ( in my opinion)are Lessacher fins...
While you guys trying to theorize, I spent last 14 years with diff boards and plenty of fins (custom and production) testing what works best fin size wise for me (132lb). So, from experience, the practical way is to match sail size to fin size, sometimes being light weight I have to go even bigger in fin size to avoid spin-outs (comparing to heavier guy).
