Going to Maui

I am taking a week off in February to go to Maui. I have been to Oahu before, but never to Maui. I am not sure if I mentioned this, but I am also a Scuba diver. When in Maui, I plan on going on a couple of dives. If you have been to Maui, or better yet, been diving in Maui let me know where I should go etc. I am looking forward to getting away from this miserable grey scale Northwest winter.
