using jigs with braided line question
So I've recently, out of nowhere, been losing a bunch of jigs on the cast. I'm no novice to using my bait caster, nor casting jigs. However I don't know if it's the filmsey rod I've been using lately, or the new leader line I got. The rod is 7' and only 1 year old. I had to sell my high end rods bc of financial problems so this one isn't graphite, and it's become a bit flimsey when casting. The new leader material is simply 12lb mono. Since this has been happening I've tried switching the knots I use, generally use an improved clinch knot. Since, I've tried using palomar knots, improved clinch knot, and a regular clinch knot.
So, is it likely it could be the rod? Could the leader line I bought have been old? Should I tie the jigs straight on to the braid? Or should I use some flourocarbon 12lb instead? Any help is appreciated.
