some dude at t-nation did a comparison... hmmm not yet there with the aestethics phil..
Flex was born with lines and shape, tiny joints, long muscle bellies, perfect insertion points.
Flex was not narrow, but at one stage his "over-developed" delts and arms made him appear so, and overpowered his chest too
But heath cannot get compared to a peak flex, IMO
Heath does have a very good back, and has probably the best conditioned/fully developed combo posterior chain of everyone at the moment
IMO, he should cut back on the arms a bit, it will improve everything else
