For the record, that mic is considered to be fantastic in tv/film field recording circles (for voice work, not music) -- there's no doubt in my mind whatsoever that it'd simply BLOW-AWAY your 66. In fact, there's a whole bunch of shotguns that'd probably be better than that 66. For some reason, everyone in video production uses that thing, but more and more, people are realizing there are better shottys in the same price range -- but I wouldn't know how they perform for music recording, I kind of cringe at the thought of that actually.
