The Frye Tri is a staple and a classic from Skip's archives. Simple, tried, and true are the guiding principles of the template designs here. The two front fins are slightly larger than the trailing fin both in terms of height and base width which allows for a tad more forgiveness without any loss of control. Also of note - all three fins are on the small side for a thruster setup, which stays true to Skip's overall philosophy of generally needing less fin while using more of the board's rail-line. These fins have a gentle amount of rake, but still a balanced profile that will translate into silky smooth turning ability and also effortless directional changes.
