First I got some P-Line copolymer in 8 lbs. test. Used it with a polomar knot for a couple weeks with a chatterbait, lipless crank, and texas rigged with an unpegged weight and plastics with out problems. All the sudden the line seemed to come undone or break at the knot. I tried to use some jigs and when I got bites, all of them broke at the knot...it seems. I also lost two buzzbaits after I switched to a different knot that was similar to a SDJ knot (watched a vid with Mark Zona), but apparently the knot has no name. Lost all lures to this knot, made sure I was tying it correctly and tested it out and I could just pull it apart. I also have some fluorocarbon line that I have not even opened due to my troubles with the copolymer.
What is the hands down best knot for these lines?
What am I doing wrong?
Do these lines need to be changed after a couple weeks on my reels?
Anything I need to know? And, any other tips and tricks would be greatly appreciated. Thanks in advance.
