Replying to K2 Silencer v. Atomic Twins and sizing up...

So I finally got the time to sit down and page through the new FS Gear Guide. I'm thinking that new skis are a must this year (the 120cm '04ish Line 1260's aren't cutting it). One major problem though, I'm 16. That makes me poor because I have to pay off the new car and works limited because I'm in college too. So, naturally, I was drawn to that "Best Bang for the Buck" list which is loaded with chick skis. Even though I have a real lanky frame, I'm not totally sure I could live with some of those graphics. The Silencers are a primo choice to be sure because they look nice and are some bargain mo-fos ($375). For twenty-five bucks more the Twins look tight on my tight budget, and got better overall ratings. I need to know what you think of the two and what length I should go with. BTW those are 155, 164, and 173 for the Twins and 156, 169, and 179 for the Silencers.

Here are the stats:
I'm 5'10"ish and about 125lbs. (THIN)
I live in Ohio: think tables and rails, and don't even dare to take powder into consideration.

Thanks in advance.
