I've see a few pics of the new Makani speed prototype, It's being tested now but I'm not sure when it's going into production. If it's like the rest of their fins It'll be awesome, Maybe a weed version as well.
I got some Speed fins with power box base made up for my twin fin freeride board it will be interesting to see if it goes any faster. Hoping there will be some wind on Friday to give them a work out.
