so i got fishing line new in the box all over my house braid, mono, floural, dental floss you name it i got stuff laying all around the house....with that being said so when i say new in the box i mean never used some spools of line i have are about 6-10 yrs old and have not been used yet so is this line still good to use since it is unused or is there a shelf life on the line meaning dose it get stale or dry rot or whatever or is it still good to use ??
