Just did a run of glass-on wood fins. I really love exploring all the completely different feelings you can get from the different types of wood and the way the grain is orientated. The dark walnut widowmaker set is for a 9'6" Mavericks gun. The walnut is really rigid and make a really stable,fast gun fin. The other two are salvaged redwood and tinted green paulonia. Great flex and spring for higher performance single foil twins.
