I use these Clouser Minnows in sizes 2 and 6 for bass and the 2/0 in Chartreuse/White and 2/0 Silver Shiner in saltwater for blues, stripers, reds and trout.  For the bass I usually use a floating line. For musky and in saltwater I use the Scientific Anglers Sonar Sink 30 Warm 350 grain fly line with a size 2/0 Clouser Minnow.
