The Fin
Kevin Connelly’s KC Tri — the all-round thruster set for middle-weight surfers, FCS compatible, in solid fiberglass.
A three-fin set built around smooth, powerful turns rather than sharp pivot, with enough tip flex to let the fin unload at the end of an arc. This is the solid fiberglass version — the heavier, more positive-feeling lay-up of the two. The template runs 4.67" deep on a 4.56" base, 15.71 sq in of area.
How that reads
Tip flex is what separates this set from a stiff thruster: the tip gives a little under load and springs back as you come out of the turn, which is why cutbacks come round with less effort than the template alone would suggest. The body stays firm, so drive and hold are not traded away to get it.
Who it suits
Shortboards ridden by surfers in the middle of the weight range, in everyday surf through to solid waves. It is a one-set-for-most-days choice rather than a specialist template for one kind of wave.
If this is not the one

From True Ames
A powerhouse for the middle weights — enough area to hold and drive, enough tip flex to keep turns flowing rather than stiff.
Our take
Run it on a thruster shortboard or performance hybrid when you want smooth, powerful turns and the planted, connected feel of solid glass, especially if you fall in the middle-weight range. If you want the same template lighter and livelier, go Hexcore; if you'd rather slide the tail loose than carve through it, look at a release-oriented quad instead.
More About This Fin
The KC Tri Fiberglass is a True Ames thruster set in solid fiberglass with an FCS-compatible base. The template is a medium thruster outline with moderate rake, a solid base, and flex concentrated in the tip rather than the body; the solid-glass layup makes it heavier and more planted than a foam-core fin. It is aimed at middle-weight, all-around surfers on thruster shortboards and performance hybrids, and the same template is also offered in lighter Hexcore construction.
