I've been fly fishing now for over a year. I've only been fishing regularly since march (when I finally got my own rod). I've never used a strike indicator, just me, my rod, my line, my fly, and the fish on the end.. Am I missing fish all the time because I don't use one? I seem to catch quite a few fish on most any given day. I suppose when I am drifting my line downstream and my line is slack an indicator would probably be quite useful, but when I'm lake/pond fishing, or fishing down/across the stream my line is usually taut. I don't drift my line down much, but that's because I've never caught a fish that way, but is the reason I've not caught one due to my lack of a line indicator?
And also, will a piece of bright yarn work just as well as whatever is in that bag of indicators at the fly shop? They look like yarn to me.
Thanks for your far superior knowledge...
