Some on here will tell you not to bother Gizmo, but I always remove mine, and wind them onto large plastic spools.
Can't see any sense in leaving a good line tightly coiled onto a reel for 6 months.
I use the corrugated plastic drainpipes that are used for sewerage systems, approx circumference is 1 metre.
Just cut them up, they make ideal spool storers, and cost nothing.
It takes minutes, and when you respool, they have NO memory whatsoever.
I use quality lines, that should avoid coiling, but I still do it.
A happy nerd.
