This has probably been discussed before now! But what in everyones' own personal opinion are the quality speed fins on the market at the moment?
I am in need of a new fin 20-24 cm for my 50L Isonic Speed and if anyone could make any recomendations it would be greatly appreciated!
cheers 
Jordan, check with these guys in Tassie, Izaak is probably the best if you can track him down. They are right onto what is needed over there.

JUST NEED MORE WIND NOW TO DO MORE TESTING ... BUT THATS LIKE WAITING FOR CHRISTMAS WEN YA 5 
Hi Jordan, Steve and I are about to get some C3 Slingshots, you could consider getting a 21cm for the iSonic 50. Should be a good alround speed fin for your weight. If you want one, let me know.
Jordan, one of the Sa speed demons (Carl) has a 24cm C3 Venom in buy and sell.
I have only used a 24 techtonics F1 falcon that came with my board and that sure seemed sweet never let go and gave me plenty of confidence to get me over 40 for the first time.

"Techtonics F1 Falcon" is still the best all round speed fin.
Lots of brands have tried to copy the techtronics F1.
However, they fail to use the correct correct grade of G10.
There is G10 & then there is G10. (cheap G10 & expensive G10)
hey guys, thanks for all the great feedback! It was between the vector delta and a C3 venom or slingshot. Eventually I ended up ordering a 23 Vector Delta. Hopefully this latest addition will increase my chances of finally hitting 40!
cheers
Good choice Jordan, i reckon a few people will be buying them soon cause the are bloody brilliant.You are certainly the next to do 40knots.
