Of the WWF tag teams of the late 80s (Rockers / Bulldogs / Hart / Demolition / Strike Force / Islanders etc) which two teams consistently had the best matches with each other?
Same question, but for late 80s NWA (Andersons / Road Warriors / RocknRoll / Doom / Steiners etc)?
Harts v. Bulldogs by a landslide for the first one.
For the second one, you're kind of mixing eras there, but the Rock N Roll Express worked a bunch with various combinations of Horsemen and it was usually pretty good. But Rock N Roll v. Midnights is the real answer.
