Almost like having slalom fins in your waveboard! Lift, drive and speed for onshore conditions. Great for ealy planing and jumping. Also surprised us with their DTL performance but you'll need to use your rails for powerful turns as they don't have the same grip'n'whip in big cut backs and snaps as the flexier fins. The smaller rocket sizes are designed to be used as front tri/quad fins, or most importantly as rear trailer fins where the upright and non swept template is ideal. Plenty of lift, speed and drive.
