    Very versatile.

    Originally only used AM2 trailers but grabbed these and it is surprising the difference. With wide tail boards a lot less delay. In small waves front L- AM’s & in bigger waves medium KA’s. Have recently borrowed a set of the new Dumpster Diver fins and used the sides (AM medium) and I think this is my fave combo. Will be buying a set of those ASAP.

    Rayon de virages courts

    J'utilise les Reactor en quad pour la vitesse, le rayon de virage est vraiment plus court que les Performer et cela améliore la maniabilité de ma planche mid-size.

    Fast and spicy!

    Ran the quad set-up on the 5'10 fish for beachy fun. So fast and still loose enough for tight turns. Definitely helped the froth factor on days where I probably wouldn't have paddled out!
