So what's wrong with trolling a fly? Ain't that what lots of fly anglers do with woolly buggers as searching patterns until they get into the fish? The idea is that you're going to catch more fish longer the time your fly stays in the water instead of in the air, right? If fish ain't rising, you have to do some moping about until you get a strike. So what's to do but troll? Or is there a more P.C. euphemism to use?
