Firewire Machado Twin Keel Fin Red/BlackThe first set of keels I rode were on a Skip Frye fish around the time we were filming Seedling they were hand foiled Larry Gephart fins that I think were referred to as 'straight backs'. Basically, they looked like plywood that someone cut out and foiled; they were beautiful. And that's what originally sparked my imagination as far as fishes and keels go.
