Frog,
Some years ago I used to want to hunt with a now-out-of-business outfitter that killed lots of BIG racked bucks in the mountains east of Afton. I regret not getting around to doing it.
If I were lucky enough to be in your situation, I would mention to your friend that you want to hunt in one of the units around Pinedale, or Afton and rely on him to help decide.
Good luck!
