I used to do this, but it works better if you fill the reel using the pencil/chopstick method, with the line coming off the bottom of the filler spool. Much less twist this way.
For the OP, if you need more than 8# line on your spinner, you will have better luck with braided line, Like Power Pro. 15-20# works great on 1500 to 3000 size reels.
He used a line winder of sorts I guess is what you call it. All I know is that with the new line, it will constantly loop off every time I cast. I will try the Yo-Zuri Hybrid and see how that works....and we shouldn't use one of those contraptions right? I've never seen him use it before he usually just leaves the spool on the floor then has one of the kids run it out to rewind it if that makes sense. I really don't know what I'm talking about but I'm learning lol. ;D
