You won't go wrong with Toledo or Rayburn. Fork, Ivie, Chambers, and Falcon could be good too. Depends on how you like to fish and what your goals for the trip are really.
For just plain numbers of decent fish, Fayette, Chambers, and Squaw are hard to beat.
For the chance to catch really big fish or a really big bag of fish, Toledo or Rayburn... maybe Fork.
To get away from pressure and have a chance to catch a big fish, probably Ivie... maybe Falcon.
I have heard rumors of fish being caught at Choke... but nothing substantiated yet.
