Another thing to mention is the stiffness of the fins ..carbon ,fibreglass ,or plastic .
The real stiff glass fins will give more drive ,good for heavy dudes .
I still quite like the original naish fins which are softer ..it doesn't seem to buck you off as much when your flying down a big one and hit some chop ..size does matter

so does stiffness ...geez ...FINS ..
i think every board is different and will like a different combo .my x32 Hokua is a live wire with quads and will go anywhere ,put a thruster set up and it very much a straight line approach but is good for down the line surfing .too bigger fin like 8. And 4 rears it leaves the water and almost impossible to turn .unless. Your riding the tail and stall it in the pocket .get some fins and swop about .

This is just some of the collection of back seat spares ..

Nice vid Rick .when I grow up I want to be like you .

i need to get some more fins .

Ive got some full carbon ones coming in a quad set .
