Around here the bows are generally 'in' the feeding lane, like a fat kid at the desert table at a buffet. The rainbows seem to like to spend a little more energy as long as they are in the feeding trough.
Browns hang in the back eddies and slower flowing water near overhangs, below pouroffs and ledges. They like to ambush things kind of like bass. They love to hide by a big undercut rock or bank.
I find the biggest Browns in 'the slowest deepest water near the fastest water', generally in bigger pools and very deep.
A good way to insure browns over 12" is a 3" streamer.
The rainbows here are picky, but will often allow several casts in front of their face, just waiting for the one they like.
The browns seem less picky about the fly, but cast to them more than three times and they are in hiding, spooked for a good 15 minutes.
For brookies I use small dry/dropper setups higher in the creek; not as sure about selecting for them though except for geographically/elevation.
Of course, there are times that all the rules get broken: big brown on a #20 midge, rainbow on a big streamer, brookie down in town...
But yes, if all I have been catching is rainbows, I will start fishing slower deeper water to find the browns.
I still have not done the 'rocky mountain grand slam'; brook, brown, rainbow, cutthroat all in a day. Very possible around here though with a little targeting.
