Fishing line storage

How long can you store mono and fluorocarbon ? I keep it in consistent temperature and it's not exposed to any type of light. Will it eventually degrade some how, even though it's never been spooled on a reel? Some of it is 3 or 4 years old.

I remember reading a Stren rep saying under the conditions you mentioned that it's a very long time- almost unlimited. I would spoilt up and keep an eye on it. (just like any other line)

I agree with Doug. Unspooled / unexposed and you'll be fine. Spooled is a different story being that memory will cause issues.
