This is another great collection of Wrestlemanias - although WM 11 is a big letdown.
WM 6 has of course Hogan v Ultimate Warrior - a truly historic bout.
WM 7 highlight is Macho King v Ultimate Warrior career match - it needs to be seen to be believed.
WM 8 best match is Bret Hart v Rowdy Roddy Piper - an epic for the Intercontinental title.
WM 9 is a good event despite it always getting criticised - the best match on this is the tag team match between the Steiner Brothers and the Headshrinkers.
WM 10 has the famous ladder match between Shawn Michaels and Razor Ramon which is a classic. Bret Hart v Owen Hart is a must see also.
WM 11 is a poor event but worth a watch.
Overall a must buy.

I like this set it has the classic Wrestlemania 6 match Hogan vs Warrior
wrestlemania 7 Warrior vs Savage and Hogan vs Slaughter
Wrestlemania 8 B Hart vs Piper and Flair vs Savage
Wrestlemania 9 not the best Wrestlemania B Hart vs Yokozuna
Wrestlemania 10 Has some classic matches such as B Hart vs O Hart and the amazing ladder match with Michaels vs Ramon
Wrestlemania 11 Diesel vs Micheals
This is one of the best Wrestlemania sets you can get.
