The EA Quad Control Series, designed by Hawaiian shaper Eric Arakawa, is a medium size Speed Control fin with a Ride Number of 3.0. Master Hawaiian shaper Erica Arakawa created this set to provide hold and maximum speed in fast, heavy, barreling waves. The solid fiberglass construction features a single layer of uni-directional carbon fiber for weight reduction and response, making the EA Quad setup a go-to set for chargers like Reef Mcintosh during serious Backdoor days.
