Hi Dean,
I like the looks of that one as well. I didn't give it much though when I was making it but after I finished it I realized that I had carved a mini greenland paddle blade with a groove down the middle. I haven't learned to roll with it yet but during pool skills sessions a couple weeks ago I was using it inside a paddle float to help develope my skills for hand rolling. It's been fun playing with it! I guess I'll have to make a harpoon and play some more!
