Silly sounding question but I went to use my rod with SpiderWire Ultimate Mono 12lb line to throw poppers, but when I cast the line, it  looked like a slinky?  I literally could not straighten it out. When I took the line off the spool all the line just kinda of "slinkied" or coiled in coils the size of the spool.  The line is only about 30 days old? 

 

Is this normal?

Spinning reel?

If you have access to a boat you can drop it behind the boat and let it out then reel it back in and that will help remove some of the memory in it. And don't put anything on the line, just let the line pull out into the water.

No its a baitcaster, and no boat.

I found that the longer mono sits the more it coils & the more often I use it the less it coils.

That's what is commonly called "memory" in the fishing world when referring to line and yes, most any mono, flouro, or copolymer will get it to some degree. If you tie your line to something solid and walk out further than you can cast and stretch it almost to the breaking point it should take out almost all of that coil.

You can purchase line conditioner to help reduce memory, though I personally only use it for really, really heavy mono. Several casts will straighten it back out, especially into an actual body of water. Stretching it will help as well, just be careful not to damage your line.

Thank all, I do have a line conditioner and will use that as well as stretching suggestions.

Coils will disappear as soon as the line begins to absorb water.

I don't know if this is exactly true. i used to use camo Siege line, and before I used it on the water, it formed large coils and was pretty much unusable on my baitcaster. Even when I used it on the water,  the coils still were there, but were just a bit smaller and less. And a day after, all the coils were back to their original size

 

Overall, I would suggest using a copoly or supple and low memory mono line.

I find this to be true for the lines I use.  I'll hold the rod tip in the water for the first few casts to help more of it get wet faster.  Many people swear by Big Game.  I find it to have more memory than Siege.  Both coil after setting awhile, but Big Game causes me more loose line on the spool after casting at first.  Getting it wet like I mentioned quickly resolves the problem.

A few casts, and a quick relieve will work the coils out.
