While I prefer a 7wt for most streamer fishing with sinking lines from a boat, the White/Norfork area is one place I’d probably guess might call for an 8. I haven’t had the chance to fish there, but friends of mine that have said they used 5-7” flies and 300 grain lines for 25+” browns. That’s 8wt territory in my book.I have been looking at the youtube stuff about the Northfork river and the big browns they are catching and just trying to outfit myself for them. I did see one of the guides say they use TFO cause the warrenty is good and quick to replace rods they break. They also say they have gone up to 9wt. rods. I already have 5 and 6 wt. rods, just don't know if I should get 7-8wt or not. They are all using big streamers.
