Tippet material longevity?
A fly-fishing author, and shop owner, wrote that he replaces his tippet material every year because he doesn't want to lose a good fish due to tippet failure. I've gone to fluorocarbon, so this would be really expensive. I have separate "vests" for trout and smallmouth, further increasing the cost.
My tippet doesn't get sunlight except when I'm fishing. Tippet failure is rare, probably a reflection on the size fish I catch, and usually involves something like a sharp rock.
How long to you keep your tippet material: one, two, three years? Three years seem reasonable to me.
Also, how do you convert lbs., e.g., 20 lb. mono, to x's, e.g., 1x tippet?
