I have about 20 twin fin's. I feel I'm pretty committed to the the design. But that's nothing compared to Dave Rastavich. Regarded as one of the world's best free surfers, Rasta is a twin fin afficianado. According to Squidforce his whole collection of craft for the Hawaiian season is twin-finned (above is his 15 board Hawaiian Quiver, all of them twin fins). Stay tuned to see what goes down in Hawaii. I expect Dave’s performances to be groundbreaking and anything but retro. Check this video of Rasta riding various configurations in 'The Free Way'
