Cool, sort of a cupped face spook shape. Like 'em.
Very close to a predator as well. Put a bevel on the head and cut a lip instead of a cup, no weight or a belly weight, and I think you'd have a swimmer.
Thanks for the comments guys. I guess they are cut similar to a nike. I made a few of those last year. Maybe that shape was in subconscious mind when I made these! I'll keep that in mind if I ever screw one of these up while making the face.
