I hear folks all the time saying buy fresh line. The thing is...who knows how old the line is that you buy at the store...it could have been sitting in a warehouse for months or a year or whatever before that store gets it. I buy line on sale and stock up with it...but as sunlight is the number one destroyer of fishing line...I store it where sunlight cannot get to it. I also store it inside the house where the temp is controled so it gets neither real cold or hot. I have never had a problem with it.
