Extra bootsole adjustment on medium Naxo n21's

Ok so here's my dilemma:

I've got AT boots with 315 mm bootsoles and Alpine Boots with 326 mm bootsoles

Medium Naxo's run 280-324mm, larges run 320-354mm

I'd like to be able to potentially use both boots with the same binding, am I completely fucked?

nxo1's are 324mm

nx21's are 340mm

BCA has a typo on their website.

score

thanks marsh

now to decide whether to try to score NX21's or Dukes

all things being equal (ie price and such), id say go with the dukes. i like the way the naxo's ski'd compared to a fritschi, but have had, and seen, alot of breakage issues.
