Apropos of some posts in the other thread (first one referenced above):
If you want the new rule from the horse's mouth, look at the top of page 3 (9th page of the file) here:http://www.fis-ski.com/data/document/equipment0506.pdf
What it means, exactly, is harder to say. Presumably, if you buy a 2006-07 race stock ski, you should be able to rely on the manufacturer's marking. That might
be the case for this year's skis, or for non-race-stock skis, but that doesn't seem 100% certain to me.
I'd suggest you either (i) don't worry about the new rule or (ii) locate the appropriate person at the USCSA and make a phone call or send an e-mail message.
