Guys I need some info on US box fin Positions, Up untill now all my boards have had power box fins so it makes where you put them very easy. I've just updated my 95 Fanatic freewave(power box) to a 93 JP Single Thruster(us box) and need some info on fin positon and what it does.

The new board has fixed positions for the thrusters but US box for the main fin, I've yet to get the board out in good conditions to see what happens when I change position of the main fin. If anyone can offer advice on what happens with the change in position I would be grateful. Also does it work the same if I run the board in sigle fin setup compared to thruster setup, and does rider weight have anything to do with fin position. Also does it make a difference in waves compared to high wind bump and jump conditions????

Thanks for any Help...

Cheers Jase.
