All the named guys had a phantastic front lat-pose. But it`s hard to compare Athltes of the late 60`s/early 70`s (Oliva) with guys who trained 30-35 years later.
so for for me: in the 60/70 s it`s Oliva
in the 80` s it `s Haney
in the 90 `s Dorian Yates
after Year 2000, this pose it`s not the same like before, because the big guys of the new century also present a much more blockier midesection than the Athletes in the decades before.
maybe one guy which could also be on that list ist Orville Burke from NY (who had to quit BB because of serious health problems he suffered a few years ago...)
