weight-on-the-bottom rigs have been used for eons in the rest of the fishing universe. This whole "Drop Shotting" thing in the bass fishing world is another name for it, from what I gather. We'd use two hook rigs with a weight on the bottom all the time while ice fishing for perch and stuff. Surf fishing with bait, we'd use a pyramid sinker or wire-leg sinker on the end, with a hook/leader tied a couple feet above. The options are pretty much endless. There's no reason to think it could be any less effective for fly fishing! One definite advantage is for snags(on rocks, not fish)- quite often the sinker is what gets snagged, not the hook, and with split shot on the bottom rig, if they get snagged they can just be pulled off and your fly will be free. Could be the next Big Thing. You should do some more research then try to publish an article about it before somebody else takes credit. I don't understand "Crunchy" paralleling your idea to snagging ???
