Fluorocarbon line is a fairly new innovation that has only been around for about three years, I think, but I'm not sure
I've never used it but from what I've read it's main feature is there is no stretch, and most people go to braid for that any way. The price for a 200 yd spool runs from $14-$18. Might be worth a try if you don't mind trying something different.
