1993 was his all time best, but you will notice that his waist was terrible:
he lost his waist long before 1993.
The lat spread shot in the first post is obviously impressive, but of course, anyone's waist can look good in a lat spread, and the pic doesn't show the horrible lack of thigh cuts in his quads because the pic is taken from the waist up.
dorian had bodybuildings greatest ever front lat spread
but only if you don't look at his quads!
