My own impression is as follows: I've played them several games on ICC in the past, and I have watched them play others. The thing is strong, but no stronger than other programs. IE I have this strong feeling that the new Hiarcs is probably better, for example, without exotic hardware, based on lots of games Enrique and I have played on ICC prior to CCT. I'd never say Hydra is weak, but I'd never say it is head and shoulders above the rest either... it is just very good, nothing more.
