Great lecturer - when I took Part III he stepped in for a few sessions when the regular lecturer for QFT broke her arm. His notes are always pretty clearly explained. Equally importantly, I've found he's always really responsive if you think you've found an error. (And very patient if the original is correct, and your "correction" is a mistake!)
