...It seems to me that if they have an easily adjustable cuff cant adjustment they might be able to make small adjustments to their benefit. I know this slightly changes the alignment at the ankle of the lower leg and foot but is this really a big issue for small changes? ... In many people's minds this type of cuff (dirty) canting is a no no. I'm not sure I completely agree. I'd like to hear both sides of the argument.<HR></BLOCKQUOTE>
Unless there is a problem related to severely limited range of the ankle joint, I agree with you totally, and for the reason that you just gave: Two degrees difference in how the ski is laying on the snow will make an enormous difference, but two degrees difference in ankle angle is of much less consequence.
In fact, for the sake of argument, I'll go you one further. I would say that if you have (a) enough range of adjustment in the boot shaft angle, and (b) have either a fairly "normal" foot or an orthotic that will bring your foot into alignment, then you can use this very convenient adjustment mechanism to verify (on-snow) a proposed cant angle before doing any irreversible grinding and without undertaking the more tedious process of installing and changing a series of under-binding wedges.
In fact, I have used this procedure on my Tecnica Icon XR's to emperically determine that I need about 2 deg on the inside of one leg and 1.5 degrees on the other. With the cuffs in this position, the outside of each foot is, of course, being forced up at the ankle relative to my lower leg.
Fortunately, this was easy to counteract in this particular model of boot. They incorporate a screw driven wedge under center of the the footbed that roughly allows you to adjust the posting angle of the footbed. Between these two adjustments, I have found a *very* comfortable and effective foot/leg environment for skiing.
Once I have lived with these settings for a while, and establish that these cant angles are OK, I will probably have the boot bottoms ground to these angles and be able to return the cuffs (and moveable wedge) to the centers of their ranges and iterate from there (if necessary).
While people usually think of the base of the boot as fixed, and that the cuff moves side to side above it, I think that one can quite properly consider the angle of the lower leg to be the reference so that adjusting the shaft angle adjusts the angle of the bottom of the boot with respect to vertical.

PS - BTW, I fully realize that the screw driven wedge in these boots is really to adjust for high or low arches, but with a thin but stiff piece of plastic between it and the footbed, it becomes an effective, adjustable posting angle control.
