Everyone is talking about four fins, but there are many different four fin set ups and it would be nice to hear about the merits and/or drawbacks of some of them.
What about direction of the back fins in relation to the front fins? I have seen some stand up "bat tails" in Santa Cruz where the back fins are almost straight ahead(like a trailing fin of a thruster split into two side by side smaller fins).
Four fins...?
