This Trifin set has longer side fins compared to the center fin. These fins have great holding power yet are not so big as to cause stiffness in tight turns needed for small waves. "This template is what I use on my 6’2″ to 7’2 boards. The fins have moderate flex and have the ability to surf up in sizeable waves as well as quite small surf." -Wayne
