I'm not a euro nympher but man, it does seem like a way to hammer fish. I prefer small streams where euro nymphing is definitely not the most advantageous method of angling. Yesterday I was on a tiny stream just tossing a dry with a nymph dropper off of it and shooting it through small lanes in the vegetation. On bigger streams I've Tightlined using my fly line out of my rod tip, but never went mono rig. Maybe I'll try it. I feel I've more or less perfected indicator fishing. There is more to being really good at that tactic than most realize.
I've seen my large local limestoner being hit hard by euro guys. They seem to get popping up everywhere. Who was the guy with the blue Subaru covered in fly fishing stickers with a weird rack on top parked at the 3rd Street bridge? If you read this, you'll know where I mean. You parked beside my old rusty red Silverado. I bet that person is a forum member here.
