Replying to JSkis vs. Armada vs. Line

I'm stuck in my decision for which skis to get for next season. Here are my choices: Jskis Tropic Thunder Part deux 184cm w/ 98underfoot. Armada Alpha X 182. And last but not least Line Chronic 185. I'm skiing in amazing Iowa so most of my riding will be park. I do make trips up to the UP of Michigan so thats my reasoning for looking at not just straight up park skis. Any comments whether serious or sarcastic are greatly appreciated.
