dive buddies with different training and configurations

[scubert]

I was just wondering how many people out there are in a similar situation and how they deal with things.

Right now we have 5-6 semi-regular divers in our group that dives together. 1 is adv.nitrox/deco certified, 2 are nitrox cert and looking toward adv.nitrox/deco, 2 are nitrox and are happy where they are, and 1 is not nitrox but will probably head that way.

in addition the first 3 divers on the list of 6 are MOSTLY DIR in gear configuration, the other 3 are more recreational.

Right now when we dive it tends to be a break down of who is breathing what and who is equipped with doubles vs singles.
Obviously this could change as it becomes a matter of 'who is going down for 1 hr, who will be down for 30 min.

I'd be interested to hear how all of you deal with your group of dive buddies all headed in different directions in terms of training, etc.
