You should pick up the 2006 World Championships from Seyberts through the AZ Marketplace. They still are running that killer deal of $12 for the whole set. I believe it includes two of Engert's matches and it will give you a good chance to see his straight pool game:
The match between Engert and Robles gives a good example of Engert's rhythm. He also played a match against Rempe in the 2000 US Open that Accu-stats has.
