If I were booking a trip, I'd look at Canyons, ARTA, Mackay, and ROW in that order. Different types of trips from quite luxurious mint on pillows zero work and fine dining to helping unload boats and setting up your own tents so many ways to do the trip and different costs. If you wanted to do just MFS, those plus Middle Fork Rapid Transit and Helfrich. Helfrich if you want a fishing trip.Like Bunion said, most of the outfitters are pretty solid and will provide a good trip. Not many bad outfitters up there and shitty guides don't last long.
