Why hasn't anyone said Blake Richardson from BTBAM yet? That man has got all the tools from speed, technicality, slow jazz rhythms and brush work. I would say white walls and swim to the moon are the best examples although he recorded himself tracking Obfuscation in HD. Although I can't post the link for it just type blake richardson obfuscation in Youtube and you'll find it.
I LOVE Derek Roddy, Neil peart of course. Keith moon has always been up there on my list with Portnoy. Divine Heresy is fast but kind of meh not too inspiring.
For just speed I'd probably say Shannon Lucas from TBDM
