After initially starting this thread, I have watched numerous videos on nymphing and discovered dozens opinions on setups. Kelly Galloup is the only one who puts a split shot on the bottom of the rig (where legal) and did a good job of explaining his logic. However, he is the only one, I saw, who uses that method. He also had good reasoning for using the perfection loop for droppers. Most of the videos used a Thingamabob (Sp) for the indicator, if at all. In any case, nymph fishing seems to be very effective and logical when there is not a good hatch. I am just now getting serious about giving it a try this Spring. Of course, I have asked for and will consider any advice. Thanks to those already responding.
