Can't go wrong tying a basic wooly bugger on a jig. If I'm trying to emulate a minnow, I'll tie it in white or silvery colors and leave off the palmered hackle. Black and olive also work well. I'll usually fish a size 4 down to an 8. Once you go smaller than that it gets hard to tie.
Strangely, I've also had a lot of luck on trout with a four colored jig I tied to emulate the Strike King Mr. Crappie Tooty Fruity tube. Dark blue body with a pink, yellow and chartreuse marabou tail. No, I'm not joking. Who knows what they think it is, but they sure want to eat it.
