I'm a big soft hackle guy, especially very early and very late in the season when the fish are not moving their fastest. Soft hackles create a lot of movement in the water even when retrieved very slowly, or just fished on a slow drop or dead drifted in the local creeks.
Peacock, black, and olive seem to be best for me in cold weather, with various brighter colors (and hare's ear) doing well once it warms up a little.
