Replying to Help me pick out a ski!

First off this is only my second season back skiing (had a long gap where I didn't go to the snow). I am about 5' 9" and weigh 165 lbs. Currently I am riding on some old 2002 (i think) Line Mike Nick Pro models 171cm. Got them for $50 with bindings. They are stiff and I want something that I can butter. Currently I ride about: 40% groomed, 40% park, 20% pow/trees. I want to focus more on riding park now as its pretty fun. I would like one of those fat skis to ride in the powder (just go back from some knee deep powder in tahoe, crazy for spring skiing).

So basically I would like a fat, all mountain, but slightly more park ski. Also have a smaller budget so would be looking at later season skis, no new stuff for me.

Here is a small list of some skis I thought would be good, but am so tired of reading to narrow it down.
