My rods are stored in an overhead rod rack in my barn 24/7 which is unheated year round and I never have a problem with fluro except for a little minor line coil which is easily fixed by stretching it out and putting a little tension on it, much like a fish pulling on the other end. I also have also left my lures tied to the line and never had a problem and I'm 68 years young. JMHO
