Steve I run a bunch of of different set ups on my rods and reels. Two of my spinning rods i use 8lb braided Fire Line with a 6 foot Pline Fluoro leader that I use for jigs and worming. The braid will last for 5 years, the leaders I'll have to change out at least a couple times a season. All my rods and reels that have mono in different sizes get changed at least once a season. My pike and muskie set ups I strictly run 50 to 80lb braid, again I get at least 5 years out of them. I've never had any braid of any size ever fail me. Fluoro or mono only ever fail at knots, I get a little lazy sometimes in retiring is what I attribute too.
