Thanks,
I never thought about right or left foot forward.
I don't think it applies to starting off... I unclip with left, and start riding with right foot at 1:00 or 2:00.
But, rather if you are say standing on the pedals without pedaling such as going over bumps or around corners.
Putting weight on the left crank with the crank back will reverse the direction on the crank around the spindle (clockwise looking from the left side)
Left foot forward, weight on right crank puts the same stress on the joint as you would get from pedaling (counterclockwise from the left side)
One doesn't get the same reverse torque if both feet are generally moving forward.
I am a little surprised that anybody is actually making Octalink V1 cranks. I know there are a lot of 6500 and 7700 cranks out there, so cross compatibility is nice, but I'd expect the choice to go with either Octalink V2 or ISIS.
