It works perfectly in both. The template is specifically designed to handle 2+1 setups well, providing the stability and control you need, but it also functions as a reliable, maneuverable option for smaller single-fin shortboards.

The stiff fiberglass construction provides a very consistent, predictable feel. You won't get much whip or spring out of the turns, but you will get a solid, reliable hold that makes the board feel stable and responsive when you're driving through rail-to-rail transitions.

This fin is primarily designed for shorter boards. Its moderate base and rake are optimized for the tighter turning radius and responsiveness required by single-fin shortboards or 2+1 setups, rather than the long, drawn-out turns typical of traditional longboarding.

Because of its moderate rake and base, it is an incredibly versatile template. It excels in average, everyday conditions where you need a balance of drive and maneuverability, rather than being specialized for just heavy barrels or tiny, gutless surf.

Yes, fiberglass is denser and heavier than molded plastic or composite fins. However, that extra weight often translates to a smoother, more 'connected' feel in the water, which many surfers prefer for the stability it adds to their setup.
