you can fish a trout fly under a natural cork bobber,tip it with one of the little Berkley power baits or a tiny piece of worm.I have had a pretty good luck with the powerbait that's chartreuse and looks like a little caterpillar. Sometimes the tiniest of split shots to keep the bait down ,sometimes a dry fly that floats will catch them on the top,the float just gives you a way to cast it on spinning equipment. Light line....if your water is stained use a line color to match.They will be picky abut the fly color and shape.

Greatest finesse presentation there is I think. But every little bugger that swims is gonna bite it.
