If you get into the spool a bit and the lines straightens out, they should be OK for a typical sport or stunt 1/2A. But they will still be a pain in the butt to take care of. That is why lots of guys have gone to the Spectra type fishing lines. I've bought some but have yet to try them out, just too busy. The spool says 400 feet, so you might6 as well see how it handles by trying to make up a set of lines in the typical manor. If it doesn't work and you can't deal with it, then you know you at least tried and then throw the spool away!
Type at you later,
