I have a f-one surf 5'11 (See epikoo.com description).

It comes with very standard DFS fins, but is compatible with FCS fins, so I am looking into upgrading the fins.

-The board is a tri-fin

-This is a description of it:
"The board packs some extra volume, thing which provides better upwind and planing performance in less consistent conditions. The rounded pintail, coupled with the wider nose, assures natural turns and a quick response in surf. The single concave bottom design, complemented by an optimized rocker, improves early planing abilities and assures flawless control even at high speeds."

-I surf mostly in Egmond aan Zee, which is rough beach break waves.

-I weigh 73kg

I am not so skilled on wave board yet, and I will also use it as a lightwind board. So if I add new FCS fins to it, I will look for something that gives stability rather than snappyness at the moment.

Are there any fin recommendations out there?

Maybe you should contact Versus since they are selling F-one boards.

Beach break at Egmond? eh no.

I suggest u learn to ride with your wave board and when u get the hang of it start tunning.

Go for a bigger set of fins for better low wind performance and more stability. E.g. FCS M7, which have a wider base and more depth.

Je kan vinnetjes vergelijken op de FCS website. Dat geeft al een aardig beeld van wat je belangrijk vind aan een vin en de vergelijking met andere vinnetjes: http://eu.surffcs.com/eu/products/fins/thrusters.aspx
