Tremendous fly and spin fishing opportunities on White River, Norfork, NFOW, and Taneycomo. I'm not sure what you're looking for that you aren't finding.
All the local trout shops are plenty helpful IMO. They can tell you what the trout have been doing lately. The Caddis hatch will likely be on the wane. Sulphur mayflies are spotty at best, but it can be awesome if in the right place. A little early for hoppers, but you could find some that would bite it.
generally Big flys on dry run, normal size on White, and small stuff on Norfork. You want heavy stuff to get down and stay down in the current on NFOW
cant go wrong with size 16 and 18 zebra midges and Ruby midges, happy meal combos, and scuds.
Good Luck
