I agree with the Peak Performance Boyancy, that is a good one. But I think I might add Underwater Naturalist and Night dive. (Ok that is what we DID do....) I mean every dive is drift and every dive is off a boat. You are going to get 'trained' in that for free, more or less. Naturalist teaches you some stuff about what you are looking at and Night dive gets you out on, well, a night dive. For us AOW was peanuts on top of the price of the dives anyway, so why not take it. JLyle nailed that one.
