There was a go who marketed these small stickers to place on your reel and you could write the line weight on them...they used to be for sale on basstackledepot.com...don't see them anymore...but I know the guy and I will see if he is still selling them or who he sold the item to.
me personally...I can pretty much know whats rigged since I don't use to many sizes anymore, including on my spare spools..i used to use the plastic spare spool clips and color coded them and you could write on them with sharpies.
