So far all I've tried are AM2 fronts w/ EA rears, both cheapo white Fg futures as my main break is super shallow reef. Worked and allowed me to very much enjoy this board but I am not experienced enough to know much better.
As I've posted the best i've used yet were the futures jjf fronts& 4qd rears. Next surf I'll try the jjf tri and the machados too... I think depending on your size and hability, a slightly larger fin will able you to push further the rails limits without sliding off.
