Unforntunately, I can't find any rear relaxed shot like this of Yates from 93, which would be a better comparison since he was at his best. Ronnie's shot is from the 2001AC, I would have liked to get a rear relaxed shot from 99 for him.
here are two relaxed shot of him in 99 spreading his lats.


but they are not very close up. Still, they highlight the taper dorian never had.
I really don't see what is so impressive about having such a wide back if your waist is almost as wide:

but apparently,the dorian fans cream their tiny jock straps over this.
the AC Ronnie shot is impressive for detail, but he is scrunching up his shoulders to show off his detail, not spreading his lats just yet.
