    quad fin as twinner

    just picked up a 5 fin from my shaper. The fins it came with are the fcs "stock" quad fins and the rear fins are interchangeable. Since they are symmetric, can i use one as a twinner middle fin in a thruster setup?

    Talk to your shaper, he should be able to explain the dynamics of different setups.
