Glad to see you got Roddy. That'll be great. A few other names to throw at you for future reference:
Mike Mangini - great work on LaBrie's new disc.
Kevin Talley - Great young drummer from Misery Index, Dying Fetus, Chimaira, but has a lot of versatility. link here to an audio sample - http://counterstrikerecords.com/main.html
Flo Mournier - he's got some extreme type chops and speed. www.flomournier.com
Deen Castronovo - Yes, he's in Journey, but maybe he'd want to play some technical metal again and he was the master of it. Someone needs to get this guy back into a place where he can showcase his true abilities. Could likely be contacted through Mike Varney.
Derek's a kickass drummer, allthough I don't find his work in Hate Eternal very interesting. I liked Tim Yeung better when he was with them. The demo's on his site are Awesome though, and his technical abilities are seriously extreme.
