I wonder how everyone else is?
Mostly conditions-dependent. Most of the time Duval County's problem is it's sort of flat-faced and soft. So I mostly use an assload of rake like the Jordy or the CI. Gets and holds speed. More distance per pump, holds speed in a bottom turn around a section or a roundhouse. I use big keels in sh!t like Bean Bags, GG G10 keel, or the NVS Stampy, sometimes with little side bitey quad trailers. Goes fast and projects in logmush.
If it's a little steeper I use the F8 or Pyzel. Sometimes when I'm riding a small-average wave shortboard with 0 fear of redlining it, on the small side of the board's sweet spot, I'll use the Roberts Large. Lots of sweep but a little undersized, so it's more responsive and tight radius than Jordy but projects a better than the F8.
Some boards (Baby Buggy) the bigger swept fins don't really make it any faster down the line, just less responsive/quick. Sub Driver and Puddle Jumper HP go fast and carve great with swept fins and get snappier with upright fins.
GG thruster/quad set have gone good in every board but seem to like clean conditions vs very stop/start surfing hopping around the chop.
