some more things:
1) why do you think Neil Peart's studio work is crappy? :D
2) ''many live dvd's of both'' ?! ok, everything's clear about Bonham, but Jojo? The only dvd which as much as I know is out there with him is the Modern drummer festival 2005! Please tell me what other records do you have!
i was being sarcastic about peart. and i have that modern drummer DVD that he demonstrates his heel toe technique, and some of his studio work.
