Hi All ,
after a bit of your vast wisdom here , got myself a tiny 5'8 fish for small mushy waves , in 78 kgs and currently have fcs g'3 s in it but find them to lack drive and speed anyone have any suggestions on what would be more suitable fins for speed / drive in small waves , old school fcs plugs in the board tri fin .
help would be greatly appreciated .

Udo , I use the same C-drive Twins on my personal bds...the quality of the fins coming out of NVS , all G10 , best construction available...everyone should get the G10's NVS fins....

Hi Hastoes , what dimension board are you riding and what weight are you?

You could be experiencing too much fin, which means, when more pressure/speed is applied to the fin , your weight /board dimensions can't control all the pressure so the fin lifts out of the water.
C-Drives have such a longer base than a normal fin.....even when I was at 95kg's I still used small c-drives....but my hull designs give a loft of lift ( concaves) and drive from very hard edges....
In big guns we have always used smaller fins as big fins feel like they are spinning out , when in actual fact the fin lifts out of the water.....smallest gun fins ever on AB's channel bottoms....hope this helps....send me dims and weight and will be a lot more precise on fin size.

Sorry regards to reply, been on a work bender. Really appreciate the feedback @brutus. 87kg myself , 5ft 11/3inch height
Riding a Firewire Evo.
5'8 x 20' 1/4 x 2' 11/16
Just thinking that ive maybe reached a ceiling with the quad set up on this board. I've been riding the evo models in the same dims since 2016ish . Had 4 of them haha. Rode it in heavier conditions up to pushy 6ft canguu but fading memories tell me that was on a more upright thruster set up. I'm thinking the c-drives coupled with the actual speed generated by the board design in ballsy waves, produce too much speed ? When im running them in average conditions for the area ( 2-4 ft ) they give me more control, speed and release in every turn. The feeling of generating speed through a turn on these fins are a world away from any other fins ive tried.

Hi Hastoes, been lurking reading the c drive comments so thought I'd chip in...
I've been using them religously a few years love them in 2+1, twin +1s, tris and quads.
Really like the new nvs feel , the different foil makes them seem more responsive and the g10 is sick.
I actually like the quads sized up relative to other guys my size. I'm 5'9 70kgs with chicken legs and my 5'10 kirk bierke has medium fronts with large rears. Incredible control in late drops but its geared towards hollow reefs and i dont/ can't do turns on it lol. Would put smaller fins in for beachies.
6'4 also a kb round tail has medium fronts medium rears. Magic combo for me does tubes and turns.
I've used grom size thrusters in a Ian Byrne 6 channel 6'4, and another chunky 9'6 gun.
Ridden some thrusters with larger side fins and a smaller center too. Not super into thrusters usually but that gives you release if your struggling with that.
Definitely depends on your board like brutus has said and troy is a legend and always has time to dial your fins in. Hope that helps
