If using side-bites, would you use the future fins SB3 at 3.25 or the SB1 at 3.50? See http://www.futuresfins.com/futures.html (longboard fins) for description of base and area. Thanks! http://www.futuresfins.com/futures.html
I have, and use, both sizes-designated as 325 and 350-and play with the center fin size and shape on boards 7-6, 8-6, 9-4, all with Futures sides (they’re specified). Get both, they’re inexpensive. Play with single fins, too. I’ve recently thrown the Lausch 4 5/8 thruster sides + a 5" center into the mix. Results across the range of boards vary from magical to laughable. Play and learn.
