OK, obviously there's some amount of weight that is too much. But I'm

Learn the tuck cast first, and how to make a good nymph leader (the thinner
it is for long sections, the better it will sink quickly and not drag.) You
might also want to read up on Frank Sawyer's *original* pheasant tail nymph
design and how it affected sink rate.
