I have a 2008 North Fish which I haven't used yet and need to set up the foot straps. Can anyone tell me if it is OK to ride it with the foot straps in a central inline position rather than set up with one end just off centre? Does it really matter or will this cause ankle or knee injuries?
Thanks for your input.
I always ride with them in the central position, but I gybe the board. Some crew never gybe, so I can see the benefit of offsetting them.
Regards ankle / knee injuries... from what I hear the main cause is when one foot comes out, and the other stays in .. the board then rotates and twists your ankle/knee. 
I have the 2009. Really this board rides best either with no footstraps or as I mainly do just the front one in. The back is set too far back unless you want to add holes. It was designed for strapless freeriding and it does perform better with the back foot out and further forward when planing then move it back once in waves. The front foot strap is good forvthose mere mortals who find it hard to get over large chop without losing board. Great board for those getting into strapless freeride very wide and stable to practise switching feet. Do bid downwinders as you will be spending a lot of time in water!!
I'll come clean .. I did my ankle/knee on the weekend with straps. Ouch.
Been making the transition from strapped to strapless over the last month, and it's been great fun.
Did the front foot only in the strap idea for a while (and the back foot out) to get the hang of it. I almost busted my ankle doing that, and decided it was a bad idea.
Was strapless yesterday, having a ball, and borrowed a friends board which had straps. At the stage I'm at, strapless is really "delicate", but can charge really hard with straps. :-)
Anyways, was charging hard, full of confidence after being unstrapped & now strapped in, and a wave somehow got me .. happened so fast, can't remember exactly how. Just lots of pain, hurt the big toe, ankle & knee .. pain in the LCL mainly - in some strange way I feel "lucky" that it's only a mild injury, rather than annoyed at being injured at all? Weird. 
Such is sport... 
I like having my straps very loose. Help to keep the board on in the chop and getting vert, but saves the ankles
Straight and loose, need to do little shuffles to get toes closer to the edge
But i prefer strapless until the surf gets too solid
