For bass my "go to" bugger is a bead head tied in various color combinations of orange, lime, chartreuse, green to simluate sunfish. For stained water conditions I use solid white and maybe use a soft plastic curl tail in place of a marabou tail or even put a propellor blade at the front of bead. I usually use a #2 hook. I've caught bass up to 4 pounds on those patterns. Next to a Clouser, Woolly Buggers are my post productive pattern for warm water species.
