Replying to Sigh...another what skis thread...

Alright, so I hate to do this, but, this is a "what skis?" thread.  My buddy is about 5'1, 100 lbs, and skis pretty aggressively.  We're on the east coast so we'd be hitting groomers and the occasional pow day when we werent in the park.  We looked through the Buyer's Guide, and found 2 possible choices: 159 K2 Silencers ($375) or 156 Line Chronics ($550).  Price is a small problem, um, anything under $650 is prefered, just because his parents would be buying...so yeah, yay or nay on these to choices or throw a couple different options out there. 

Thanks!
