I use a camo line made by bp. It is every bit as stong as rated and while using ive noticed a marked increase in number of fish caught. 6 lb. line is big as I use. It is strong enough to lift 2 lb plus crappie onto tower where i sometimes fish and drag most crappie through moss plus it presents 1/32 oz jigs in a life like manner . Rate of fall is probably as important in getting strikes from crappie as anything. I've tried hi vis yellow and red line they just dont produce for me. I think they cant make out the broken pattern of camo . Plus I make sure to trim line back to a clear section when i tie on.
