Select vs deboichet-size
I am about to order select S11 for my ultrasonic.
A friend of mine tells me that select fins should be 2 cm smaller/shorter than deboichet.
An example: I want a new fin for my ultrasonic and overdrive 9.5; should I buy select S11: What size?
Recommended by remi is deboichet 58. But select S11?
