Gimmick some one said ? wtf Yeh i have orded a custom 10' sup with Swallow tail, from a goldy shaper, the 5 fin choice does me, single, twin quad triple gotta be all good, i want a choice according to the conditions.
Surfed twins a couple of (dozen) years ago, love the feel, though put in a single fin on a different day and the feel is unreal as well.
I think PIROS it depends on whats gunna go blow your hair back on the day, eveyones different.
