Replying to Armada ar7 vs. Armada el rey

hey NS. I have a ski decision problem. I'm thinking about picking up a pair of either armada ar7's or armada el rey's, for this season. being 5'9 ish, and about 130 pounds, the 166cm(164) seems perfect. (i'm skiing on a 155 now).

I ski a mountain with no park and bad conditions (but is ten minutes away) all week... so I need a ski that can handle ice and groomers and all mountain well.

also, every weekend, or whenever I get a chance. I ski my backyard setup which contains many rails and jibs, or the monthly resort trip-> park,  so i need a good ski for rails.

(Big air isn't as important to me because I only hit big jumps a couple times every season. [when i make it to a nice mountain)

the bottom line. I've narrowed it down to these two skis, and i'm wondering how much better the ar7 is for the money, and will it fit my needs. reviews or opinions would be nice.

(line chronic crytonite? line afterbang? line blends? line step ups?atomic punx? armada triumph? K2 domain? rossignol s4 jib?)  skier type: 3+

please help. this is supposed to be for christmas haha...
