A pretty good list, but I don't think Eddie Van Halen should be on it. If there is Van Halen, there should be Blackmore. If there was Blackmore, there should've been Page. And so on, and so on. If the list is for metal guitarists, they must put only metal, not hard rock guitarists. And I am completely agree with Iommi being 1st. The influence and innovation in playing is way more important than technique, so although Hendrix and Page played hard before Iommi, he is the most influential among the metal guitarists.
