Lilac times, Mick's words:
The template was based on 2 iconic fins, the Greenough 4A and the Lance Carson rake. I took the leading edge of the 4A and addedthe tip of the Carson. The idea is to have drive from the overall Greenough-esq design yet still retaining push through the turns with the added surface area in the tip. The straight up and down outline allows for solid hold on the nose. A great overall log fin.
