If you want an honest answer, not that good at all. They're way too narrow to be good in any significant amount of new snow. 84 underfoot and only 113 at the nose. You're going to sink a lot in anything over 6" of new snow. There isn't really a park ski that is good in powder, they're completely different skis. If you're doing both extensively then I suggest picking up two pairs of skis. If not then you'll be fine with an occasional off-piste run.

173 would be a solid size for you. 181=too big, 166=too small.

It would be a pretty big mess up to the magnatraction. I tried them, and I noticed that when they are center mounted, it felt even more awkward than normal magnatraction. I would say that the better ride normal overrides the better ride switch, and to mount them at the recommended, or maybe a little further forward.

ah i meant i am certain on 181 haha my bad

I would almost say that you want the longer ski, for landings and all that jazz, but if you are dead set on the 173, I won't argue. As for the durability, they will hold up for years to come.

Teleskiing these things is cool. I definitely wouldn't recommend a soft binding, though. Hammerheads are perfect for them. You could put some Bishops on there...if you HAVE to...Bishops are just...well...they're for Teleskiers who think they need to beat alpine skiers, and the rest of us chill, layed-back free heelers know that gear is only as good as the skier. That being said, Hammerheads kick ass, and you can always get the stiffy springs. Hammerheads don't break like Bishops, and they cost half as much. As far as mounting goes, put the end of the wings on the binders at the center magne-traction 'bump' for optimal control.

unless ofcourse you are handycaped and you only require 1 NAS to fit your chair. this is true, i have seen it

Hi. As part of Lib Tech's marketing design for this NAS (Narrow Ass Snowboard) they say that you buy one narrow snowboard..i.e. Ski (for a premium price, around what you pay for 1 pair of skis...$698.95), and since you can't just ride 1 individual ski they will give you a 2nd for free. So, to sum that up, you buy 1 ski for $698.95 and you get 2nd ski for free.... To save you a headache backcountry.com just made it easier and sells the pair for one retail price!

Probably not, I've never heard of that kind of deal at Backcountry.

The low tips won't effect sking in pow or crud, line elizebeths, bacons, and prophets all have fairly low tips and they are powder skis, same with salomons pocketrocket.

in CM: 12/8.6/11.3The manufacturer's catalog can be found online (just copy/paste): http://www.libtechnas.com/This has dimensions, explanation of the recurve, and fun propaganda.They updated this recently (November 2008), so check it out.These are actually called the Pipe NAS (not park) by the mfgr.

They require you to mount them at the midsole (The boot center will be aligned with the narrowest part of the ski, or in this case with magnetraction, aligned with the center of the **largest** bump); which is farther forward on this ski than even most park skis. Mounting ahead or behind the midsole messes up the bumps. So no, but almost.

they weight about 7.5 pounds
