Hey ya'll
I got a question for you!

I am riding a Mistral Syncro '07 92ltr board! on Port Phillip Bay aka BUMP AND JUMP!
It comes with the stock mistral fin 27cm.
And
Sometimes/mostly i use an OLD SCHOOL 1995 Wave Fin with it that is 23cm.
Anyway, this fin is just getting to old and slow!

What are some
good makes and brands out there, that will keep me going
super fast, but still being agile enough to make quick turns.

and also, what size do you recommend!
Thanks guys and gals!
Steve
