If it was Viscious line, then I'm not surprised. I know a lot of folks like this line, but I've tried it in three different weights and it pops a knot quicker than just about any other line I've tried. It won't be on any of my reels any longer.
On the other hand, I see no need to use light line when Crappie fishing. At one time, I had reels with 6lb and with 10lb but there was never an increase/decrease in catch based solely on line size. So now all my Crappie reels have 10lb Hi Vis P Line or Golden Stren. I did use Gamma line last year, but it's pricey and I didn't see no advantage over P Line. Spool up with some 10lb and be done with it!
