John's been prototyping his new signature fin for over a year. The initial concepts came from his favorite F4 Techflex, but his new life on the ASP World Tour and a late teen growth spurt required much more area than he was riding in 2011. Per him, the fin was to be a Techflex. They also added base and reduced the tip area. Drive, release and control were the primary measures, and John's effortless style proves high marks in each field.
