I've got From The Vault too, which is really good, even though it only has seven matches.
Aye but
Iron Man does take up a HUGE chunk

The selection is fab on that.
The follow up
Heartbreak & Triumph is worth getting for the bio bit alone, 2 hours worth of his life/career story, watched it again the other day and its really, really good, the extras matches are cool too. They put the
Kurt Angle Vengence match on that, and with the
Wrestlemania one on this, its great how these sets compliment each other, the
Hart Family Anthology should be a cracker which compliments the
Bret Hart one (although his bio one was a bit of a drag...)
