Very nice indeed! If you added Tim's suggestion of an adjustable beak, it would be identical to one I plan on making. I already have 3 yards .6 cuben, just need a little more for the beak (am going to go with lighter .48 for the beak I think).
I'm using MLD's carbon pole (the long one). What pole is that I see? It looks like a doubled pole. Again, looks great!
