Gabe, Since Kaimana has such a great reputation, I think it would be a mistake not to dive with you while we are in Oahu. A couple of points and a couple of questions:
Point 1: I'm a pretty big guy, 5'11" and about 235, so I seem to go through air pretty quickly. I've had experience with bad gear that's caused even quicker air use than if equipped with good gear (bad BCD hookup to tanks, leaking BCD, etc.)
Point 2: We'll have a rental car, so we could meet you wherever we'd need to for the dives, but please provide good directions unless you intend to pick us up (we'll be staying at Waikiki, Hale Koa).
Point 3: We'll bring our masks, snorkels and flippers, but will need all other gear.
Question 1: Do you use integrated BCDs for weights or weight belts?
Question 2: We've been in the pool to work on bouyancy (last weekend and hopefully next weekend), but have not been in open water since July 2010. Anything else we need to do to get ready to dive again?
Questions 3: We'd like to dive several dives while in Oahu. Any deals for quantity dives?
Hope to see you in a couple of weeks.
