I'd also like to buy 4 helmets.  When we were in the store in Nov, Ryan showed us the Smith Varient in matt black.  We need 2 adult MED and 2 2 adult LG.  Let me know if you still have them in stock and the price.  We also have some Bahnhof Bucks.
As far as skiis go, I've got the records from our rental last year:
Betsy has her own boots.  Skis were Volkl VR-63-44.
Brooke's boots were Head 265 -305mm. Skis were Volkl VR-63-40.
Chip's boots were Head 27.5 - 317mm.  Skis were Volkl XL-70-2.
Marshall's snow board was a Head 156 with Burton boots - 10.5.
Hope this helps.
