Throwing out some of my fave's from the 80s, before the WWF became a virtual monopoly, I loved the late days of the NWA
Von Erich's - always loved Kerry... amazing to think he did a good chunk of his career on one foot.
Magnum TA / Nikita Koloff ... great feud at the height of the cold war
Midnight Express
Rock 'n' Roll Express
Fabulous Freebirds
Road Warriors (they were the baddest of the badass mofo's, then became soft as shit in the WWF).
Abdullah the Butcher
Scaffold matches, War Games, Crockett Cup, PWI Magazine, Starcade (the birth of monthly PPVs)... ahh, the good ole days.
