Replying to Quiver management

Alright, I need some advice. First off I'm 6'4 190 lbs and i ski on the east coast. Now, I have a pair of 187 MSPs which i used last year for everything (park, all mountain, and a trip to Utah) but as the new season rolls around i decided that i want more specialized skis, rather than a jack of all trades that isn't that great at anything. I definitely want a park ski, and im torn between Fischer Addicts, Nordica Ignitions, or Ar5s or Ar6s. Im also trying to decide if i should trade in the MSPs for a better Powder all mountain ski, which would probably be gotamas, prophet 100s or similar. I have a budget of about 800 dollars but id like to spend as little as possible. Thanks for your help guys!
