I checked the spool and the line is low. I will respool with with Vicious 6lb panfish mono and test, currently has Mr Crappie 6lb. I have other reels spooled with Stren some with Mr Crappie, this should be a reasonable test. One thing I noticed is, the Vicious line is smaller diameter than the others and feels less stiff.
Fur, Richard Gene use Mr Crappie line, seen it on the interwebs.
