So there are already tons of 'what dive op to use' threads. I'm more interested in the sites than the operators at this point...I'll figure out operators after I know where I want to dive. Friends will be on Maui for a week in October. I've get 4-5 days (including a no-fly day) to fly over from Oahu for some diving with them. We're open to shore or boat or a combination of the two. So, if you had 3-4 days to dive the Maui sites, what would be on your 'must dive' list?
