Why don't you tie the rod name to your store name, "Stream Flies"? Call them, "Stream Flies". Then you can branch off per style of rod like "Stream Flies River", "Stream Flies Stillwater", "Stream Flies Saltwater", "Stream Flies Bass" etc. etc.
I would not tie the main name to a specific fish type, or water type like, "trout" anything, or "river"/"stream" anything. If you want to build species specific rods later on then it doesn't really work. In other words, if your rod name is "Trout Slapper" then how do you build a bass or saltwater rod and sell it under a brand name tied to "trout".
