I love the idea but I am a scuba diver and I NEVER kick that way under water. It seems clumsy to me. I only kick that way when doing the breaststroke on the surface.
I'm not a scuba diver, but even that didn't look right to me. The concept is interesting though!
This looks to be an interesting idea.
