In reply to GravitySucks:
It's a difficult one, for me, even in situations where there's been a suggestion online of reserving specific equipment, the shops tend to ignore. Most shops will have a stock of genuine AM skis but depending on the weather or conditions, they could be popular or all out when you visit.
My best suggestions are to either (a) email the shops direct, though you might find you lose any online discounts, or (b) take a higher/expensive level of ski package online and specify what you want when you get there, not surprisingly shops are a lot more flexible if they're getting better paid. Could make exchanging skis to try out different types or models easier too.
