for the scenario that is given us here, I would do pretty much what has been suggested. But there are a lot of situational dependent strategies.
Assume light current:
Check my own air and my buddies, signal where is the up line?
when he srudges his shoulders, start heading up. At about 50' or perhaps shallower depending on the current, send up a smb -- one only. I agree with Mike on this one.
continue a normal ascent.
I think it is important, especially if you are getting a bit low on air, to get shallow first and then worry about the smb. From 100' to 50' or 40' can be only one minute so little is lost with this, but you have nearly doubled your breathing air.
An exception would be a ripping current which could drive you too far away from the boat to be spotted. Then I would use a closed cell bag and send it up from the wreck.
In a different scenario, where you have 50 minutes of deco off of a deep wreck and some current, sending up the smb first would be the priority -- but then you and your buddy should have plenty of back gas left so the gas situation would not be a stressor, only bottom time.
