IME, Gibsons were as excellent as they always were up until the '69 models. I actually prefer early reissue ('68 and early '69) Les Pauls to '50's ones, and I prefer mid-to-late '60's SGs, hollowbodies, and semi-hollows to earlier ones. Even some early '69's were still good. The SG's neck joint/angle was ****ed up in '69, and the LP's volute, multi-piece necks, short neck tenons, and large headastocks also came in as the year went on. By 1970, they were in full-on '70's mode.
As for what I was saying about volutes, ideally, they bridge the neck and the head, being at their thickest point directly under the nut. If the entire volute is on the neck side of the nut, or all on the head side of the nut, it actually makes the neck more likely to break in a fall, as it is more rigid compared to the wood on the other side of the nut.
This is one version of a "proper" volute:
Not only do the physics make sense, but it actually looks good as well.
