In the previous post I discussed my fascination with the homemade freestyle fin phenomenon...in particular how small they are compared to traditional fins, and that commercial freestyle fins were ignored by true freestylers. All the responses were along the lines of "are you nuts...OF COURSE you must have a super short fin!"
So here a photo of mine. I've found it challenging, but it works. I like Mike Burns' suggestion of the fin being wrist to middle finger length (kind of like harness lines being elbow to wrist length) but my fin is too short for that.
