I have 10 extensive clips of the 1991 ATP final between Pete Sampras and Jim Courier. It was a great match full of baseline battles. In fact, even though it was 1991 I don't see much difference in the pace of the game to today.
I also have:
1994 WTA final - Mauresmo v Pierce
1994 Masters final - Sabatini v Davenport
2000 Masters semi - Seles v Dementieva
