A 5 weight rod is ideal for most nymphing and wet fly fishing situations but for trophies I chuck and heave large streamers on a 7 wt rod with intermediate sinking line. White and/or blue clouser minnows are great for larger fish and the white bass will nail them too. For basic nymphing usually anything will work if your flies are getting a drag-free float and getting deep enough. A Prince Nymph with a small emerger dropper fly under a strike indicator (a piece of yarn) is deadly. As is a Hares Ear Nymph, Pheasant Tail, etc. Sometimes those trout seem like they would eat a gym sock off of a rusty nail if you hucked that at them. These fish are hungry and now that the water level is low, they are stacked up to the point you can almost walk across them. Good luck, have fun, and watch the generation schedule and water level if your wading.
