Karma or Foil and what Length?

I realize there has already been a thread about this, but my situation is a bit different.

I'm thinking about getting Karmas or Foils to replace my CR Lab which was a great ski, but is now banged up and has lost it's pop. Keeping in mind that my big mountain/west coast ski is the Gun Lab, what length Karma would you guys suggest since it will be mainly for the east coast and light powder days on the west coast. I'm 6-1, 200. I ski 25% Park, 25% Bumps, 25% Cruising, 25% Powder/Trees/Crud (such as it is on the East Coast). Would 185 Karma be too long for bumps and trees? Any help would be great.
