If you are going to the Smokies give Abrams Creek on the Cades Cove loop a try. I fished it a year ago March and did better than expected. Before I got there I stopped at a couple of fly shops and was told not to expect the same results we are used to on Taney or anywhere else that is stocked. I was told the avg. size is 6-10 inches and few and far between and to expect large crowds around the easy access areas and possibly high and discolored water that time of the year do to snow melt. The first morning my son and I went to Abrams creek about 7 am, pulled into the parking lot and there were already about 30 cars there. Went down to the creek and only 1 fisherman, the rest were hiking up to the falls about 2 miles away. Caught a fish within about 5 minutes, rainbow about 12 inches. Caught 6 altogether, 2 below avg, 2 avg and 2 above avg using a dry for an indicator with a BHPT or copper john dropper. During our entire 4 days I only saw 4 other fishermen in the entire park. There was no snow anywhere even in the mountains so the creeks were low and clear. Just being in that setting was worth it
As far as who wears the pants I told my wife long ago its not a vacation unless it involves fishing and she still believes it. This trip was to a cheerleading competion in Gatlinburg, but since it included fishing it was considered a vacation.
