I know this is out of date by now, but Martin Goulding did a hell of a job with this lesson. I've been practicing the stuff from it all evening (first oppotunity for a proper practice on the electric in a while) and it's a blast...great riffs, and it works pretty much every aspect of your technique. It has some great examples of Mike Romeo's tapping-that-sounds-like-absurdly-fast-and-fluid-sweeping' approach...
