I just ordered a new 5’9 x 2 3’4 diamond tail single fin. It should be ready in the next week or two. I don’t know much about center fins, so if anyone has any suggestions for a good performance fin, they would be greatly appreciated.

DEPENDS!
Your weight, width of WP, width of tail, size and kind of waves you mostly surf.
Most guys would say…8" single. It’d spin out big time on hollow 5’ surf.
I’ve used anywhere from 9" to 11" depending on speed and steepness of the waves.
