Most times I like to fish upstream with a dry or nymph. But there are occasions when I fish downstream, lobibng the fly and then wiggling line out with the current. Now, the problem comes in close quarters, where I need a short leader. Short to enable me to lob/cast and direct with the line. Otherwise (a) I"m in the bushes or (b) cant control the drift of the fly. I'm thinking about four or five feet might be about right. What are my best taper options?

Thanks!
