Replying to 4frnt question

Well I just found out that 4frnt has the 35% discount for college students, so i can get the TNK or the STL 08 models for $350 each which is rediculously cheap.  So here's the question, I'm 6'0'', 180lbs, 20 years old, and an expert skier.  I ski around 50% park and 50% all mountain including backcountry.  which ski should I get? the TNK's are 115-89-111, and the STLs are 116-84-104 in my sizes, 181 and 183 respectively.  4Frnt basically claims that these skis are both park/pipe skis and that the STL is better on hardpack.  I figure it would be better to get one set of skis that can do park and hardpack, and then get a dedicated pow ski later on.  On the "ski selector site" it says that neither ski can really do any pow, but isn't 89 at the waist of the TNK enough to go through pow? dimensions seem perfect for an all mountain ski too.
