Re: Nymph Presentation
I don't like "constantly" feeling the bottom when I nymph. And I don't fish with my fly "trailing" upstream of my shot. In that situation it sounds like not only are you using too much shot, but you are also fishing a pretty heavy fly, if thats the case you want significantly less weight in shot. I do however, like being reassured that I'm getting down by feeling a periodic tic or brief hang-up when I can't see or sense where my fly is in the water column.
I pretty much follow what Rip Tide says to find out how much to use. I start light and incrementally increase If I am worried about snags. If I know its a pretty snag free area I go in on the heavy side of my guesstimate and then work my way lighter. And you do get a feel for it after while and will spend less time adjusting, and more time getting it right on the first cast.
