There is no escaping the Doom Skull! Carry out your sentence on the Birch 9.0″ x 32.15″ Stump and OG 10.4″ Pig shapes and be held captive for life. 7 ply North American Maple pressed individually using epoxy – making a strong, responsive deck with long lasting pop and consistent concave and kick. VET concave is a custom symmetrical concave for wider shapes and longer wheel bases. This all terrain concave is mellower on mid width decks and deeper on wider boards with mid-height kick, giving you freedom of choice on foot placement.
