It’s really cool to see the responsibility fin manufacturers are taking while offering high performance quality products. If you check out the Dorsal site (they also have a Facebook site) you’ll see they did a full line of tri, quad and single fins in 7, 8, 9, 10, and even 10" & 12" hatchet fins. They are clear, red, blue and black with varying degrees of flex.
They are getting ready to do a run of stiffer fins than their current “medium flex”, which I think are good for lighter riders up to 160 lbs. on HPSB’s but need a stiffer option for the big boy tri guys.
I am sending them some plans to add fish fins to their line as every fish fin I’ve seen cost an arm and a leg!!!
