Sorry I don't post on these boards often, hence my low post count.
I don't know much about that particular outfit, but overall flying in Alaska is a whole other animal than the rest of the world. I've got my FAA PPL and I was always interested in going out there to get my tail wheel endorsement. Alaska offers a whole ton of new experiences that simply cannot be gotten anywhere else. In fact, there is a series I watched concerning pilots in Alaska. I don't know how much of it is staged and how much is real, but it was a lot of fun to watch. I think it was called "Flying Wild Alaska." I'm sure that'll give you at least some perspective of the type of training you would expect to receive out there. Hope this helps.
