Air -- good at any depth.
(This is using a pony within standard parameters, where it is a bailout bottle, switching to it is the end of that dive, time to ascend.)
If you've done the workbook, without problems, you should be fine.
A full pass through the encyclopedia can be good -- the physics and physiology stuff does, indeed, get asked.
Don't forget to review using the Wheel.
I generally agree with the second-chance approach.
If they mess up again, then public noogies count as significant repercussions:

With my pony, I unscrew the valve all the way, put a baggie with elastic over the open end.
Ideal? No, but it seems to work.
I absolutely take my regs as carry-on.
It's just that the whole thought of schlepping an 80 as a pony hurts my head.
Dry (land) weight is a pain, there really is potential for a full 6 lb swing, then you have to add lead to your off side to compensate for the list the tank would tend to produce. (being around -3 on your left side...
I'm +10 in the month and change since I stopped smoking (a gift to myself for my 47th Bday). The plus side is I know I'll knock it back down, am doing the right things (cranked up the workouts, started to watch intake), just a drag that I need to.
So you're carrying enough added lead to compensate for about 1/3 tank (1000 psi). Good stuff, I was just curious.
I went the 19 route as it was the largest I could comfortably pack for travel. No problem with local fills (I just make sure it has a current VIS)
Anti-freeze air bleed, probably -- a normal Sherwood design.

Are you talking about the little black tab shown in the link above? It's supposed to release air (bubble), the net air used up is small.
Pete beat me to it.

No problem :)
I actually ended up putting together a little note on it, because it comes up as a question periodically:
http://markfm.dynalias.org/Weighting.pdf
Crazy -- No, we understand the math, what we're talking about is 2.5% of your total weight, fully kitted. See my example on the first page, where my land weight comes out to about 240 lb (with everything, including tank), so I add about 6 lb (2.5%, or 1/40 [which is the same thing], of my total...
Question -- do the folks who use a big "pony" also carry enough lead to compensate for the change in buoyancy if you actually had to use that air source? In other words, do you carry roughly an extra 6 lbs of lead (an AL80's worth of air), so that at the start of a dive you're around -11 to -12...
You can also use a trim pouch as a pocket, the ones with that normally go around one of the tank straps. I use one that turns out to be perfect for my folding snorkel.
Good job!
I've been lucky (not luck, really) this time around -- must be my time to quit. I don't seem to have anything that I would call a classic trigger now, just the short cravings that are definitely on the random side.
Think I'll go off of the zyban over the next week -- definitely a...
