I'm not sure how much line I spool on one reel but Walmart usually has some good deals on Mr. Crappie line. I found a great price on a Mr. Crappie Hi-Viz Mega Spool 2,000 yds. there awhile back as I needed to spool a few reels with new line.
I like to fill my spool half way full. I have found that when casting or shooting light jig heads the line will cough
up a big birds nest sometimes if you fill it full.
