If I'll team up with you if you're in a different configuration is pretty situational. Are you diver 3 on a 2 person team and we're doing something resembling a casual cave dive sure come along. We're not counting on you for anything at that point.
If it's just me and one other person I want our configurations to match if it's not a recreational dive. If it's a dive that is at the limit of my comfort zone then I want everyones configuration to match.
