After riding a lot of twins over the years Jeff McCallum wanted to take the next step up in performance and as he puts it, "Put a little more squirt in his boards." His result is the Twinzer—a forgotten 80s and 90s template he's bringing back. This set has a rear fin that is more upright for pivot while the front fins get right on the rail for more bite and speed. The Twinzer will generate more "squirt" and allow for tighter turns in the pocket compared to traditional twin fin setups.
