hey everyone, i have a 5'4 JS Pier Pony with futures fins. i was just wondering what the best fins are for that board? i have the futures F4 that came with the board. and i also have the TechFlex EA fins for one of my other boards that i have used on my pier pony. and i can tell a difference but im not sure thats the right set of fins for my pier pony. what is everyone using?? small mushy weak wave fins??
