I haven't fully put theses through their paces yet, but so far these fins provide a sure footed feel. Providing drive through turns where I previously had to nurse my 5'2" fish through turns as a twin fin.
Out of the box they look and feel space age. Fully black carbon fibre with clean, sharp edges. Very stiff fins.
I can't help but wonder how a smaller rear fin would feel for this set, as when I went through really weak spots I could feel a slight drag. Maybe that's just the compromise of a quad over twin fins.
