Foam used in McTavish Endless Progression

Does anybody know what kind of foam (Clark, Walker, etc) is used in McTavish surfboards?

The cheapest foam possible!As long as its got the big M logo any fool will buy it.

The molded ones are EPS (expanded polystyrene). The custom ones are urethane from either Clark or one of the Aussie brands.

Last I checked, ET was making them using Clark, but probably a little Walker too. They get shaped on a machine in Capo Beach and sent back to Pat at ET. I know Walkers rockers are so inconsitant they usually use Clark on the machine. Probably being overshaped, just a guess. Jono

all aussie ones are burfords foam http://www.feraldave.com
