Glass fins are much thinner and foiled better; which makes the board faster, smoother, and turns hella quicker.
I strictly use the "Future Fin System" and all the fins are made of fiberglass. I have a variety of sizes and colors to accommodate any weight class. Come in and check out the JB1, JB2, or JB3.
My Quad Fin setup is more unique than the 3 - Fin, because of it's greater selection of fin sizes.
Some people like mega punch, others like it a lot looser or anything in between. Longboards are incredible as a quad setup as long as fin placement is proper. I have been shaping quads since 1981 with concave bottoms. Guns and semi guns are unbelievable as quads; move the fins further up and your 7'6" will turn like a 7'0".
These sets of quad fins sell for $63
