I'm with Hardy. For a true small stream rod along the lines of what you're after, you want a full-flex, slower action rod. And tubular graphite rods under-perform (generally speaking) in this category compared to fiberglass, bamboo, and Hexagraph rods. But there are some very respectable graphite rods in this category. You just didn't list any. I'm not a fan of glass, myself. And my order of preference runs as follows: Hex, bamboo, graphite, glass. So if I had to go for a graphite 3wt small stream rod, it would most definitely be the Elkhorn Nomad 8' for about $100. It's not a true full-flex, but it is a very deep progressive taper that gives it a medium action on the slowish side and is very soft and quite accurate for tubular graphite. It is also extremely durable for a hollow graphite rod and comes with a lifetime unconditional warranty and tube. Before I got my Hexagraphs, I fished Elkhorn Nomads and Travelers as my light duty rods exclusively for years. The Traveler is a "prettier" rod with a more conventional progressive taper (mid-flex).
When you tell me you are after a small stream rod in a 3wt. I would not consider anything over 6'6" in length. People are going to disagree with me but I can take you places where if you choose to bring an 8' rod the only things I'm going to bring are beer and snacks to enjoy while I watch the show. The places where I find the need for small stream rods the casting is so tight that a person fishing with much over 6' 6" of Rod will have to pass up 75 - 80% of the fishing opportunity's. These small streams exist from Nova Scotia throughout the North East United States and Canada and everywhere else I have fished on the continent. You just gotta go with a short stick for some places.
Although we are not as cramped (wink) that you would have to be restricted to 6 1/2' rod (my LL 2 wt is 7'9"), I am seriously kicking the idea of a nice 6 1/2' glass for the heck of it, plus it will come in much nicer for Uinta creeks. But it has to be glass or wood as I think plastic that short would be too fast for me.
with a full flex, it doesn't matter how short it is, it is going to feel great...;-)
