I would say Yates because there is too much speculation if Arnold's are real or not.
Who had better calves, Arnold or Dorian?In my expert opinion Arnold had far superior pecs and arms (the only body parts that matter ) while Dorian had a better back and superior delts and quads (Arnolds quads were smaller but had better seperation). But calves is tough because both these guys had awesome calves, not as good as Erik Fankhouser but awesome nonetheless.
arnold had fake calves?
Yates LOL why is this even up for debate hahaha
arnold calf shape is more elegant
