After watching the video of the 1980 Mr.O i thought Arnold won and 2nd/3rd was Zane/Mentzer. Arnold just had much better proportions, flow, quality and easier more size than the rest that year. Mentzer complained but he was too blocky. I didn't think it was close in the end. Video's are far better than Pics like Dorian in 1997 or Ronnie 2001, on video both easy winners, in pics don't look it.
