I`d go with Rick Wane in the arms dept.
Though I disagree, he didn't have Arnold's insane peak, I think Rick was very underrated. Over all I thought he was better, just by a hair, and more balanced than Franco. I suspect racism and Franco's clout (all from Arnold) prevented Wayne from going further.
IMHO, he was the best writer bbing mags ever had. I just cracked up when he was writing about Arnold's 1980 win he described Franco as "Arnold's Sardinian sidekick."
That guy knew bbing inside and out and had a way with words.
