Too specialized for what? DC area? Probably. What do you fish for and where? There's nothing around here that would require a 12 weight to handle. In nearly every case here it would be like squirrel hunting with a 50 caliber rifle. A 12-wt is starting to get into the weights you'd want for offshore fishing for species like Sailfish, smaller marlin, smaller tuna, mahi mahi, etc. It also works well if you're targeting tarpon or big salmon, like in Alaska. If you're throwing really big flies for musky, pike, steelhead, or some of the inshore saltwater species (like striped bass, maybe even permit), you can use a 12-wt, but you could just as easily get away with a 9 or 10-wt.
