It was already mentioned in an earlier post, so I'll just add to it. The Little River Outfitters (aka, Little River Fly Shop or LRO) carries Orvis glass rods as well as the Redington Butter Stick. (I recently bought an 8' 5 wt. Butter Stick from them). They are located right in the middle of Townsend, Tennessee next door to the post office right off HWY 312. All of the guys there are extremely knowledgeable and they will let you cast the rod. They also carry a very large supply of flies and fly tying materials. You can also order anything they carry on line.
Stopped in to Little River this past weekend and they also carry the new TFO glass rods.
