What park ski should I get next year?

So I've used my current park skis for two seasons now, and although I can still ski them, I've gotten loads of scratches into the base, I think it's starting to delam (btw, delaming is when the layers of a ski split right? Cause that's what's happening to my ski haha), and overall I just think it's time for me to get some new skis. I'll be getting these next year, so I'll most likely be getting 2011 skis. I know most people haven't been able to ride next year's skis yet, but based on what people have said, past skis, specs, etc. it would be great to atleast get some suggestions of skis people think would be good, or atleast skis that have been good in previous years. So anyways I'm about 5'5 but still growing, and I weigh only about 110-120 lbs. I've only ever ridden one pair of park skis, which are the skis I'm currently using (they're some old 07/08 rossis but I don't really know what skis they are - I THINK they're called Scratch Blasts) but I think I would prefer something fun and playful, and really soft (since I'm so light). Probably about 160-170 in length, and will be used on the east coast. I'm probably about 90% in the park (since my local hill has no good terrain whatsoever) but I do take some runs down groomers every once in a while. - no backcountry around here haha.

Oh, also, is there really a big difference between symmetrical VS assymetrical? Because at the moment I can't quite decide if I have a preference, but from what I've learned from the searchbar, it seems as though symmetrical skis must be mounted centre (which I prefer), ride just as good switch as it does forwards, and are supposedly only good for pure park, while assymetrical skis must be mounted back a few cms, carve not as well switch, although improved performance while carving forward, and better pop. Anybody else got more insight on this?


Oh and sorry for the long post and all haha.
