Aero 117 in-board or outboard strap setting for wave riding...?

[loopless]

I just picked up a Aero 117 for light wind wave riding and was wondering what the best position for a single rear footstrap. I am sailing down-the-line so normally would set the footstep in the most outboard position possible to get on the rail as much as possible for the bottom turn. But for the Aero I could use the off-center middle strap or outboard one. Just wondering if the off-center middle strap will give me enough to crank a bottom turn. I am thinking the outboard strap could be too much off-center....


Thanks
