Actually, dookey, wes asked a broader question than you did:

They're relatively narrow, so they wouldn't be a pow quiver ski, and going far aft would provide little if any benefit.
If I bought them, I'd be tempted to mount a pair of Tyrolia Railflexes 1.5cm aft of marked boot center, so that the forward-most mount position was the marked boot center and I had easy options for shifting 1.5cm or 3cm aft. The reason I'd go with the Tyrolias is that they have the best fore-aft adjustment I've seen, and would provide flexibility. Caveat, however, that I've never skied either these skis or these bindings.
