This is what Martin love says about the fin ,Named deadly weapon 3 different ones ,this one is the cheaper of the 3 ,it's the slalom all rounder ,carbon 75%, 25% glass ,made in a custom epoxy infusion aluminum mould,it gets the board up on the tail more than a G10 due to its softer flex

,I can bend it on my knee ,It quite a thin fin ,hope to try it in the next few days .very light ,very nice craftsmanship on the fin ,
a carbon GPS FULL carbon ,and a slalom racer ,softer flex ,are also available from Atomic fins

this is my 2 nd atomic fin I really like them ,they deliver good performance,the 42 G10 turned my 120 Patrik Frace into a machine ..totally transformed the board .this 44 will be going on my 127 x77 2022 Isonic ,
love fins are very reasonably price .
Atomic fins are based in Melbourne ,great service ,fast delivery ,and a Martin is a very good windsurfer and designer ,
if you haven't got a Atomic fin yet ,you need to get one
last time I looked Martin hasn't updated his website with the new carbon fins ,
I think he's been windsurfing too much

I recently got one for my Fox. It feels very different to the g10 stock fin. Much more forgiving/soft ride through chop. It makes me sheet in and hang on, even through the rough stuff. It's faster too, and I've been over 30kts several times in relatively choppy coastal conditions. I got 1cm smaller than the stock g10 fin, but it feels as though it has equal or more lift and grip. Very happy customer here.

Thanks for the possitive feedback and stoked you are liking the fins.....the website update is on my list and I will start it this week.
