Now that my fly rod & reel collection has grown to exceed the number of toes on my left foot, I realize I'll never remember which reel or extra spool has which line. Is there an easy way to keep track of line weight, brand, WF or DT, and purchase date (age), other than a notebook which I'd never update, never carry with me, and probably would lose? How do you cope with this challenge, or am I the only one so "challenged?"
