Here is what I've done with the top two buckles (you will notice the top buckle fastener has been moved more inward). This, coupled with passing the booster strap through the outer-most pulley fastens things where they need to be.
But I'm wondering about the second buckle.. can I move that to the right (left on boot) to increase the radial canting... (i.e. is that just as important as top buckle)??? Where that it, it was hard to even get the loosest rivet buckled in the inner position, but the radial cant may have been better.
(P.S. I know this may not be "techincally" radial canting, but it was described this way in The Skier's Edg., so I'm just using the term this way... please let me know about the buckle fastener position.
