How it surfs
The JJF/Futures pairing is the go-to reference in professional surf coaching content — Ombe Surf and Stab both use it as the default demonstration fin in performance-shortboard breakdowns.
Best matched with modern high-performance shortboards ridden in solid surf: Pyzel Ghost, Channel Islands Fever, JS Xero Gravity in Futures boxes.
