I've been putting a little more thought into this. It might be several combinations leading to this.
Angle of the bait
Rotation of the hook when set
Thickness of plastic
Does the fish actually have the head in its mouth or just behind the hook
Rod combo.
What does help is leaving a bit of the hook point exposed. Might hang more but you will lose less fish.
here are 2 I made. I love the top one because of the angle of the hook in relationship to the line. I have yet to miss a fish. Havent caught a ton on it but alot better then the bottom one. The top one stands free for the most part, pulls through weeds nice and the widegap just rocks. The bottom one just doesnt hold the worm right imo. I havent had much success on it either. I quit making them for this reason. IMO its a useless jig head.
Na, sometimes we just notice little things that make a bait just a bit better because of making tackle. Not saying fisherman/non tackle makers dont notice either, just we might be a bit pickier. I'm pretty picky when it comes to some of the ideas. I dont like casting and missing the fish when I set a hook. Lots of R&D time. I hope that came out right and understandable.
I have noticed when I go to a tackle shop and look around I'm not looking for baits anymore. I look at designs and colors. I put alot of thought in some of my designs not as much as some. Using angles, weight, head design, color, etc. Lots of thought goes into some of the simplest looking things.
Alot of time this year has been spent making up some concept lures. On the water and at the house. Results I've had are some horrible ones and some brilliant ones.
