Gadawgs. Moving a centre weight to the front does not move the CoG to the front, it shifts the CoG to the centre of the front section, given that the forward and rear weights are identical. But it does dramatically increase the inertia of the front section.
This will reduce the head 'waggle', but not eliminate it. In fact, for the lure to work properly, a certain amount of 'waggle' is required, but barely visible is sufficient.

Vodkaman, I liked your analogy with the broomstick and bricks.
A-mac brings up a good point, the problems you are seeing may be largely related to the density of the material you are using to build the lure.
One thing I have found makes a difference is how smooth the joints are operating. The slightest "catch" in the motion of the joint seems to magnify once the bait gets in the water.
Swimbaits are a relatively new topic on TU and with time I expect we will better understand the cause of problems such as rolling, wobbling, coming in on its side, etc.

Please do not get me wrong, I am learning with the rest of TU. I am just applying engineering principles. Also, I am reading everything that has been written, watching every video, making notes and trying to put a theory of operation together that explains everything. I don't expect to br right everytime, if my suggestions don't work out, please let me know, or I don't learn.
I promise that when I solve the theory thing, it WILL be published here.

I didn't meen to imply that move the weight forward in the head would eliminate the head motion but it most cases it will significantly reduce it.
