Im not sure who hosted and i wasn't a Super fan but i remember Happy Humphrey, Rocca, Gene Starr (think that was it'The All American') Haystacks Calhoun, Graham Bros, Sammartino,the Indian etc. Wrestling was fairly regional and 95% of what i saw was from the Northeast.
I mainly watched Studio Wrestling WIIC, out of Pittsburgh, hosted by Chilly Billy Cardille in the 60s. Loved Rocca, Ace Freeman, Eduard Carpentier. Hated Buddy Rogers. LOL!
