Perry Brunner, who fishes practically every day for crappie, says the secret to catching fish is for the lure to lie perfectly flat in the water. I think he is right. The problem is the weight of the rubber lure is generally a little heavier than the jig head. This will naturally cause the lure to lie at an angle from front to back with the tail down. To achieve a level lure you must tie the knot very tight to the jig eye and then move it around towards the hook point. This puts pressure on the line to tip the rubber lure back up.
Tie a few and look at them and you will see what I mean. It is a little tough to keep the knot from wanting to work back to center but well worth the effort. The picture below gives you some idea of what is meant (in the water the tail will be more level). Jig on the left is a no-no. Jig on the right is correct.

That’s a great hint about the jig staying level in the water when fishing straight down. If you cast out, don’t cast to hard or you could make the knot on the jig slip back to the top of the eye and the jig won’t lie flat anymore; It probably would be ok though if you are reeling the jigs in slowly, but if you let it settle straight down again it could be a problem….
Thx for the tip though. I remember doing this sometimes and it’s great to be reminded about doing it again. I will remember next time for sure now. This is a fun and friendly knowledgeable site…
