hey all
the summer surf this year has been pretty crap so far, but I brought this little 3.5" centre fin in Bali last year and decided to give it a whack with some fcs keel fins that I got given on another board
never tried them before, but it actually worked pretty well. A touch skittish on overhead waves, but on under that they were very fun, even when quite hollow. I'm running them on a pintail Smik spitfire.
They still have a lot of hold and drive, but you can kind of release the rail a bit at the same
time too.
I know this board wasn't made to work as a twin, but this set up seems To work 
I have the FCS Mark Richards side fins and the same size centre fin on my spitfire and it also goes unreal
Are those sides less keely, and more height? I do think that a twin fin with a bit more height / rake and less base would go even better!

It depends on the wave.Keels work well at low speed, where you can push on them without sliding.
Fins with a higher aspect ratio work better at higher speeds, you get grip but without the tail becoming too stiff and having you struggle against the fin power.
I used to put keels on small waves (less than waist/chest high) on my Simmons, and switching to AM twins for bigger waves.
The C-Drive is a nice compromise: a wide base for power, but a thinner head to shed power. I ended up using only them on my Simmons.(But then I discovered the Quobba, and never got back on twin fin setups)

Never tryed keels on my spitfire, but more then happy about what I use now, and what Colas wrote the C drive;s work good in slower waves
