There is very little difference between a flyrod nymph and "Indicator".......and a spinning rig with a small bobber and nymph. Especially when the fly reel also has a hightech disk drag to boot. In the Steelhead world....a noodle rod, which early models are basically a spin rod built on a flyrod blank, is used with a clear casting bubble and "Micro-jig" (or beadhead fly). Now, compare that to a Chech rod with a beadhead nymph and indicator. In both instances, the rig is rollcast or flipped within reach of the rod.....virtually no casting is often the case. The only difference is the line. Yet oftentimes the flyrodder never has more than a rod-length of flyline even in play. It's all how you approach things......
