Great. I use these fins on my other SUP surf boards as well as my Focus board for quad fin setup.
I ride a 8'2 x29 width older torpedo carbon fiber. Awesome speed and control in 1! Will upgrade to newer model eventually but having to much fun with this 1. Great board.
These are awesome fins. I use this set on my focus Torpedo 8.5". They help create just enough drive-through your bottom turn to help you drive off the top of the lip. As a goofy foot these fins took my backside surfing to the next level. Great for those steep days where you need control as well.
