first of all nas is a ski series made by Libtech.
second of all....one ski company isnt necessrily better than another, they might be a larger sized company but different people like different skis. The 4frnt MSP last year was one of the sickest mid-fat twin tips made in a while, but there were sick ones made by other companies too.
The disadvantage to buying skis from smaller companies like 4frnt, libtech, liberty, etc...is that not alot of ski stores carry them, and sales are mostly made online, so seeing the ski in person, flexing it, etc is not available like that of the larger companies. Warrantying skis to smaller companies is sometimes a hassle too, dealers of salomon or volkl and shit tend to accommodate you a bit more than others.
yea..
