the fact that Victor took an endorsement with MD when he probably could have had his pick, shows that he really isn't to smart..
IMO, Flex tends to sign guys with squeaky clean records. MD likes guys with a little more dirt on their hands. Both have their good and bad points. Flex signs rated G guys, and their content is more "use supp X and train this way". MD signs the Rated R guys who tell you "use supp Y and use this gear stack".
both have their own unique audiences. I think Vic fit the MD mold better.
