Recently, I bought a 1/4 lb spool of 10 lb Big Game, it has 1500 yards on the spool. It was only a buck more on sale than the filler spools I normally buy for the reel I put the 10lb line on. But, the reel, a Shimano Sedona 2500FB, is not used as often as my other reels, so it will take most likely more than a year to use all that 10 lb Big Game. I normally store my unused line in a drawer in my bedroom, so its a cool dark place. How long will mono line stay good stored like that? Are there any other precautions to take to extend its life? Used to have my reels spooled at the tackle shop, but started doing it myself out of self-defense, too many of those guys don't know what they are doing these days.
