Ok well generally the considered ppvs (from memory) are:
Barely Legal '97 (the very first one, there a whole collection based on the build up to this on the network just now)
Living Dangerously '98 (has a very famous spot in it)
Heat Wave '98 (generally considered one of the best PPVs of all time)
Living Dangerously '99 (big moment for one of the mainstays)
Also have you watched the WWE One Night Stands?
