If you only fish with one rod.....you will get very very good with THAT rod. You will not need any other rod. I mean intentionally landing a fly on a big streamside rock....slowly tug till falls into water naturally....bouncing flies off a log over a stream.....tossing over the log and dangling the fly just above top water...casting a quiet line out completely horizontal and letting it float gently softly down to the surface......stealth....etc. If you golf, rent clubs, get a different set of clubs each time you go....it will be a long long time getting good.
