Steamboat/Savage from WM3 is my all-time favourite. Steamboat put in some mighty fine matched with Da Man too.
Pillman/Liger for the Light Heavyweight Belt in WCW is also sweet.
Over the years, I've seen some very good Bret Hart/Dynamite Kid matches on TV, when Stampede was still televising shows. I remember a nice ladder match between the two. Also, Bret's streetfights with Bad News Allen were great too.
Are you ready for Mahkan-mania to run wild all over you?
I am in violent agreement with Messer Bulldog. Throw in the odd Easter Egg and they would walk off the shelves. Even the DVD's of PPV's with a couple of good matches and the rest filler or duds seem to sell well.
