In the past I have used the 1/124 oz. with about a size 10 hook. They don't seem to snag in the river as frequently as regular nymphs, I have tyed Prince Nymph and Copper Johns on them and done well. Bream and bass have fallen victim to them. I had an interesting discussion with a 6 lb. class LMB one Saturday morning before getting him to come over and say hello at a personal distance using my 3 wt. that is now in the bottom of the Hooch.
