I'd be interested to know all those fin guru's opinions on a 2 + 1 fin set up for a longboard v's a thruster set up.

I'm finding my UF8 quite stiff through the tail. It is a pintail and I did have the board made for bigger waves, and there haven't been any since I got it. This stiffness turns me off wanting to take it out in the samller stuff. It might be that since I have been riding shorter boards lately I am noticing it more.

I'm now questioning if I should have gone with a thruster set up.

For it's sort of a mood thing.

I still have my Billy Hamilton HyPerform Tufflite. It came with a 7 inch Takayama, and tiny GL sides. I've upsized the sides, and I really like the smaller fins overall on that board. But you need to surf it aggressively, and off the tail. I'm not always in that mood!!

Also, because I surf Point Break quite a lot, I go for large centre fins with a fair bit of base for drive. In smaller beachies, I definitely notice that the board feels stiff, and hard to turn. Yet on the points, the same set-up loves the long drawn turns on the open face, and even harder tighter turns on the points.

My EvoII feels great in all conditions. I think an 8" Fluid Foils centre fin, not a Wiz Fin, and the GX side bites.

Does Red & Blue stripes suit your board!?
I like this fin. Circa 6 inches.

Shapers make 4.5"-5.5" centre box fins that will turn your setup to thruster size.
