Ric Flair and Sting vs. The Great Muta and Dick Slater (Clash of the Champions 8: Fall Brawl - 09/12/89 in Columbia, S.C.): An absolutely wild match, it opens with a dive train that sees Slater of all people join Sting and Muta with a plancha to the floor. Non-stop action ending in one of the most memorable and controversial angles in WCW history. I won't spoil it.
The Midnight Express vs. The Rock 'n' Roll Express (Clash of the Champions 11: Coastal Crush - 06/13/90 in Charleston, S.C.): The latest chapter in the greatest tag team feud of all time sees the two teams try to have a great match while using none of their trademark spots. It's not their best match, but it's really good and very interesting if you know what to look for.
Sting vs. Rick Rude (Clash of the Champions 21 - 11/18/92 in Macon, GA): The semifinals of the "King of Cable" tournament, this is the great match they didn't get to have almost exactly a year earlier at Clash 17. A personal favorite of mine.
Ricky Steamboat and Shane Douglas vs. Steve Austin and Brian Pillman (Clash of the Champions 22 - 01/13/93 in Milwaukee, WI): These teams had an incredible feud, and this is a really cool match. The conceit is that there's a 30-minute time limit instead of the usual 60-minute time limit, so they need to cut a faster pace, and it's all action. A great chapter in the best run of Douglas' career.
Barry Windham vs. 2 Cold Scorpio (Clash of the Champions 23 - 06/16/93 in Norfolk, VA): Kind of odd on paper, but they mesh well, and it's one of the most fun matches ever to happen on a major WCW show. Can 2 Cold of all people win the NWA World Heavyweight Title?
"Stunning" Steve Austin vs. Ricky Steamboat (Clash of the Champions 28 - 08/28/94 in Cedar Rapids, IA): One of Steamboat's very last matches due to a sudden back injury, but he goes out in style against his best opponent of the '90s. Make sure to check out the Dusty Rhodes promo on the same show.
Vader vs. Dustin Rhodes (Clash of the Champions 29 - 11/16/94 in Jacksonville, FL): Possibly the greatest singles match performance of the future Goldust's career. Sting was Vader's best opponent in WCW, but Dustin was right there with him, and the result is an incredible match.
