The 2 worst that I can think of that I used were the butterfly fin and traction tape for the entire surfboard. The butterfly fin worked until you tried a bottom turn and the whole board would just shoot out from under you. The freaking traction tape, I remember buying a whole roll of it and you put in on the entire board eliminating the need for wax. Well after about 2 hours of surfing it had wore my skin raw on my knees, nipples and the insides of my legs. Needless to say I tore it off that same day. http://www.soulsurf.com.au/recently-...zy-v-fin-retro
On an interesting note I found this page when searching for the butterfly fin. Holy fin contraptions!http://www.surfresearch.com.au/f.html
