I wish that I had some good Dale Hollow stories! I've fished there three times back in the early 90's I think? Pretty much stunk up the place, although it's a great fishery. I enjoy Center Hill, Norris and Cherokee for lake smallmouth fishing.
For me, I'd rather hit the Holston, French Broad or the Upper Clinch for river smallie fishing. I love river fishing!
As far as high mountain trout fishing, I've been up there a couple of times. One of my close friends is a fly fishing trout guide up there. We caught quite a few, but I'm not really a fly expert. Pretty much did what I was told! For trout, I usually hit the lower Clinch, Caney Fork rivers and a few creeks. Much more of a U/L spinning rod, 2 lb test and rooster tails kind of guy
