I'm no expect either, but I have found swinging big flies for summer run fish very effective. You can cover a lot of water fast, without missing any sections and it's damn fun. I have heard of guys nymphing in really low clear water (spooky fish) conditions, like they sometimes have high up on the Kispiox, but you rarely see anyone nymphing. Up in BC you do see the occassional gear guy, and they always say they do well, so if definitely works!
