Plenty of BC knowledge on hand
I'm guessing there are a few reasons you haven't seen more replies. Your questions are quite basic and amenable to Google searches. Or for that matter, searches of prior threads here and other sites. So my reaction is to suggest you try a little harder and then come back to the Board with a substantive question, e.g. the Babine for the first week in Nov vs. a Nass trib in early Sep.
And of course, the Internet is so pervasive that people are now reluctant to mention a lot of detail in respect of when, what and where . . . . It's why the guides, fly shops and lodges that still provide fishing reports usually lag them by about three days so they don't have to compete with their own viewership.
All of Sep and Oct make sense. I'm not aware of any lodge on the Skeena or tribs that has a bad rap. Some are more highly regarded than others, and pricing sometimes reflects that. But more often the quality of the guiding is high and the price differences reflect either access to more expensive water (e.g. Upper Copper via heli, Babine), more luxurious lodging (e.g. one lodge employs a masseuse, or used to), or name-brand guides.
Depending on when you come and the water temps, hooks could range from #8's to 3/0's. There's a tier in Kitwanga Ron Materi that I recently came across. He ties for steelhead and salmon and in bulk his prices are very attractive. I'm using his flies just now for springs . . . not very successfully, but that's not Ron's fault. Get hold of Trey Coomb's book on Steelhead Fly Fishing (the second one) and look at the color plates of the flies and match them against the Skeena tribs he writes about. That's a rock solid point of departure.
The method doesn't matter to the fish.
