Thought I'd drop a line and update
We have come a long way with our own patch at ITST. We have now nearly all animations for our 36 Pro players and tons of courts. We have balanced the game-play greatly, between the court physics and players stats, it feel really good now. We have also made an Installer for the patch, so for less computer-savvy out there, it is now as easy as clicking "next" a few times.
Anyway, if you are into this type of Gaming, this is likely the best SIM out there at the moment.
