pivot question

[shootin4par]

I do understand that technically the spine is not a bottle rocket and that it has curves in it. Because the spine sits in the back of the body, the vague generalization of it being a bottle rocket is somewhat acceptable to me. The spine does not go through the center of the body like a rotisserie chicken.

but my main point is if people here agree with the compound pivot being pretty much the same as the pivot preffered here, how can I prevent swaying action?
