Hi
How do I get the loops out of my line that have set in my fly line they have been on the spools for a few years?
Bill
pull it off and stretch it!!!
Allow the line to twirl downstream with no hook, that should remove any twist in the line. Then stretch it to remove any coil
Regards Mike
A few years??? Easy, strip off all the line a throw it in the trash and get a new line.
Look at it this way. You can use the whole line as an strike indicator. 
If I think there is too much in the way of coils, I will take the coils out by just stretching the line a little bit. I will do this in the field after rigging up my rod at the car. I just put the line around a convenient smooth-surfaced object. I use the sideview mirror of my car. I will walk backwards with the rod&reel on one hand, the end of the line in the other hand, and the line looped around the mirror. When I have walked back about 30 feet or so, I will have about 60 feet of line off the reel. I just pull it a bit with both hands to stretch it a little, then wind it back on the reel and go fishin.
If my line has set a long time I’ve been know to stretch the line out between the railings on my deck on a very warm day and just leave it there for hours [clean it then too]. I’m not sure if it does any better than what Gadabout describes.
