Additional Info
"Works great on all boards that are designed to turn aggressively. It's where the Involvement's blend of drive and looseness can be put to full advantage." -CJ Nelson
CJ rides this fin in his involvement logs primarily but also rides it in his Parallax and Outlier models, and gliders when the waves get larger. This fin has less area and a touch more rake than our Power Flex model making it more maneuverable for Small wave slashing.
