I am not sure if this has been discussed before, but last week I was organizing my messy fly boxes. I wanted to put all Stillwater flies in 2-3 boxes, then I moved on to my dryfly box. To my surprise I had some flies in there that are close to 20 years old AND in good condition. I drag many of my non-used flies with me and use one only if the opportunity calls. However, at least on lakes, I stick with several of my usuals. So, here are my questions: Can any of you relate? Does anyone ever just chuck them? I am trying to be sensible any bring moving water flies with me on rivers and still water flies on lakes. Sometimes a fly works in either. As I told my fly fishing buddy (when the fishing is slow and we still see a trout splashing or some being caught) I say...I must have the correct fly in my box somewhere, but I don't have the time to test as to whether to use emergers, tiny nymps, etc. I try to use good judgement and watch the bug activity, fish location, weather etc. Stuff just drives me nuts during non-productive times. Kind of like too many flies, not enough time.
