They sure do swim well.
You make really nice lures.
I've had on and off results by putting some of the ballast just slightly behind the front hook hanger, and also just slightly above the center line of the lure, nose to tail.
In my lures, I make a through bore from side to side, and add two smaller ball bearings. Ideally, the bore is three bearings wide, so there is just enough room for them to move from side to side, with one always in the middle.
I have achieved a wide, intermittent hunting action this way, with the lures swimming along for a full second, and then moving approx. 2' to the side before they continue swimming for another second, and then they move back.
I had hoped for a more radical "hunt", but this is what I've been able to do, so far.
The lures I made to hunt are 2 1/4" plus a square lip that lets them run down to 4', and they hunt on a slow or moderate retrieve.
It is very hard to duplicate this every time, and small things, like hook and split ring sizes, and enhance or kill the action quickly.
I think the raised ballast increases what Dave called the instability of the lure almost to the point of blowing out, and then the movable ballast kind of kicks the lure over, but then it corrects itself.
It was fun to try, but I've stopped playing around with it because it is too hard to duplicate consistently, and I'm lazy. Hahaha
