Have you tried Stockfish 1.4? It's a derivative of Glaurung and is very, very strong. (It always plays interesting, aggressive chess)

No, I haven't, but added it to the tournament. Thanks for the tip.
It'll take about two weeks to play all the games.
Just realized that I've forgot to post the result of the "extended" tournament. Stockfish turned out to be a Toga/Fruit killer.

Run a tournament for some of the free engines I have with their default settings (hash table size was set to 512MB). They had 2 hrs for the first 40 moves and then 1 hr for the rest of the game (~6 hrs/game). The tournament had 6 rounds (126 games).
Here are the results:

Toga, Rybka and Glaurung got about the same number of points and were significantly better than the others.
