flex was good bc of full muscle bellies (before the synthol) and a very small skeletal fram and small joints. he had great shape and size to his arms, great abs, and some of the best upper back detail ever.
other than that i think he is a bit overated. he showed up for most shows in good shape and with the above mentioned attributes, he won a lot of shows. personally, i like the bigger and freakier guys, but flex did look good. but he did have some flaws, no back or shoulder width, cuts in his lower body, and weak calves.
