I would say Hoerbl b/c of his arms and leaness. I really like Gerrit Bandenhorst's physique a lot as well. He just looks goddamn powerful. That is the physique I would aspire to if I moved up to the SHWs someday. That is as far as true strongman competitors go. But some people are going to argue that Ferrigno and Franco had the best b/c the competed in some of the early comps.
Yeah. I second and third that! Bill's delts, back, and forearms would've put any bodybuilder in his heydey to utter shame. Well, maybe Lee Haney's back excepted...I don't know how big Lee's lats were in the early eighties (?).
Curtis Leffler also had a freaky physique, with all of that crazy vascularity.
