Zane and Nubret (and others of that era) had a harmony of body parts. Muscles of one area seemed to flow and match other parts of their body, in that harmony. Each BB'er had individual characteristics that set them apart from another.
Not a question of Zane vs Nubret, but which type appeals most to you.
Present Pro's resemble cartoon characters, which I think the magazines, book and video producers are forcing on the general BB'ing public. When your a teenager, you might believe it's cool to look like them. As one matures, being honest with yourself, the current Pro's do look a bit ridiculous. Their health conditions are borderline ER room stat. Only my view but; Judging all this from many personal viewing of them, in the gym and out.
