Done both spots on Kesagami now. Fished with the lodge and Gardiner Air, now bought out by True North. With True North you are limited in not being able to go down the arm. Most never go down there so little lost. The service at the lodge is top notch, so it was a great place to introduce my wife to the fly-in. They pack you up a great lunch with coffee or whatever you want. If I were young and money was an issue I'd do True North. Having said that, you are beat if the weather is bad. Your cabin isn't on Kesagmi and you have to boat down to the path to get to the boat cache. If the weather is rough that is not the nicest trip.
On another board another member raves about Taltson bay on Great Slave. Anyone ever fished that?
