I don't have many issues with small baits tearing at the jighead because all I use are collar-less heads. The larger baits I use for jigging walleyes and the occasional smallie are often fished on hooks with keeper wires. I long ago stepped away from heads that have the retainer barb cast onto the head. Still, I get tearing issues occasionally because I use a soft formula plastic.
I think this has been tossed around and if so I apologize for being to lazy to snoop any info up here. I am thinking that maybe a clear dip of a firmer plastic at the head end of some of these baits that are prone to tearing when fished with a keeper an answer, in part, to the issue. I seldom fish baits with eyes so the dip isn't needed for that purpose and the bait I most often see the issue with is narrow enough at the head end to allow a cover coat without dampening the action. Has anyone had any luck using a stiffer formula plastic as a cover dip just to make tearing less of an issue? If you have done this, how did it work? Is it worth the time and bother?
