Damn, I'm wasting my time actually posting about surfing these days....
anyway...
Thinking of converting one of my boards into a five fin box quad/ thruster convert.
From what I understand from articles written by Rusty and McKee, perfomance (ie not fishy) Quads work best when the fins start from a thruster frame work. So the front fins don't need to be changed and you can just add two rears...
anyone done this or have a five fin box- convert? how were the results? when do you ride what set up?
