If you want a fun all around ski here are some recommendations:
ON3P Jeronimos - super fun ski, does well in the park, but also can shred all over the hill
2009-2010 K2 Kung Fujas - Last years Kung Fujas were alot more of an all around shredding ski than this year. I have them and love them, they shred park, but because of their waist size and flex pattern, they can still rip around the rest of the hill
Surface Double Times - Similar ski to the Kung Fujas underfoot, but just a little different. I believe them to be a little bit stiffer than the Fujas, so they would hold an edge better on hardpack.
Line Chronic Cryptonites - the most park oriented out of all the skis I'm listing, but are still sizable enough for fun all over the mountain. Buttery enough to have fun jibbing, but stable enough to handle big jumps and what not.
Armada AR7 - this ski absolutely destroys park, and is really really fun. I don't have any first hand experience with it all over the mountain, but I'm sure it would suit your purposes!
Good luck choosing a ski, you can't really go wrong with any of these!
