Mostly with me it depends on what river/stream I'm on....there is alot of "private" water in colorado, which dictates which way and how far you can travel....but on the gunnison river, I fish/hike upsrteam....and fish back also....I tend to fish alot of rabbit hair zonkers/buggers....but also nymph alot too.....right this next weekend I'll be fishing the colorado....upstream by glenwood springs.....midges, streamers, buggers, zonkers, eggs, and san juans
