Just remembered (have email out to friend double checking) but pretty certain that a friend had a Wilderness shaped by Richie West in early 70’s that had dead flat rocker behind foreward wide point but also full width single concave for most of the length, flat out the back. Nowhere near as deep as Cole is doing now but still dramatic for the time. Bladed out rails with high domed deck. Not an easy or forgiving board to ride but fast fast fast in the right spot, right wave
