Only reason why flex appears smoother in hams is because of pic quality tommy posted 93 vs current hi-def pics. As parker said, flex could not have been in better condition, everyone that follows bbing knows AC 93 flex was unbeatable (on the day vs competitors of the time).
On other hand, phil has a very good back. The man is mostly delts & arms, has a comparatevely weak chest and width, but he has a very good RDB, great back, hams, very dry. Its an underrated facet of his physique, because what people first see is these huge arms.
93 AC Flex Wheeler vs Heath? Flex wins IMO.
