One80 Surfboards - Pivot fins

Anyone try this?

Would be nice to try the fin system but looks like you have to buy the whole board.  Seems like it would be a better business model if you could just buy the fin system.

Blakestah had a similar fin system.  Whatever happened to him? Several sway guys gave his system a try I think. I don’t think I want my fins moving around when surfing. Maybe when I was younger and more athletic. Mike
