Here's my latest design, the Woody 2.8. I made it roomier than the original Woody, for those long days out. It's all about comfort, speed and carving, not designed for 3-D. I'm sticking with my original twinzer (4) fin configuation. I did refine the setup a bit and seriously factored in the twin fin option. I often run just 2 of the 4 fins on my other craft.
