Stumbled onto this site , insane looking SUP fins.

Yes I have a Becker, a Bat fin and one of those swept back Ninjas in transit. I asked the designer, Larry Allison about the pink Ninja that sticks straight down but he stopped making them because he doesn't think they work so well. Larry's a really nice guy and his fins are being used by a bunch of Starboard team riders.
We need Mark Paul to bring out a SUP Kanga-cock fin like he did for windsurfing.. 
..and maybe get Multi-fins to bring out SUP Strada fin..
