George, When reading your post about your teams of three divers, a question came to mind, which I'm sure you know the answer to: Do you select team members to work together based upon their gas usage rates? I'm sure not all of your divers have the same rates, so do you classify them as to gas performance? Are these checks done before each dive (in case you've got someone with a minor chest cold that turns them into a Hoover)? Do you simply work until one of the three members reaches a certain point in his gas managment, and begin your exit? Or does each diver carry the amount of gas that he himself requires for the duration of the dive? You guys have some serious gas managment to work out for the kinds of exposures you describe, which made me wonder about the answers to these questions. Just curious. Kevin.
