Golly...it's got me fooled pretty good. And to think, all that time I 
actually thought it was better.

I use the counterlung volume for fine tuning.  For the first 20 hours or 
so, your bouynacy control slurps wind because you're used to using your 
breathing and you're not used to that much collapsable bouyancy.  
However, once you master it, you have FAR better control than you ever 
did on scuba.  I no longer have to hold my breath or in other ways alter 
my breathing to hand solid as a rock in mid-water.  It's great for 
photography.  If I'm a bit too light, I snort a little gas out my nose.  
If I'm too heavy, I tweak my shoulder in a certain way and a tiny amount 
of diluent is added to the loop.  This not only adds volume directly, but 
also drops the PO2 slightly so the solenoid fires a few extra bursts of 
O2, further adding volume.  It takes time to learn the techniques, but 
now my ability to hold vertical position without even thinking about it 
while hovering along a vertical wall is better than it ever has been 
before. I don't have bondage wings on the 'breather now, but I will be 
adding them to the Mk5, if the 5 doesn't already come with them.  I think 
I'll only use a single-bladder, because the counterlungs are my backup 
buoyancy.

Incidently, on the angled thing, the trick there is to establish a firm
"center of buoyancy" (is that a real term?) in the right place - then you
can roll in any angle and hold it without effort.  That's the main reason
I used aluminum 100's on my open-circuit rig.  The rig was neutral with
little or no gas in the BC, and my body was neutral with no wetsuit or
weightbelt (therefore didn't change with depth), which means I didn't have
to struggle to hold an angle.

Apology accepted, but in fairness, I have to admit that I originally did 
believe there was less drag.  I haven't gone back to see if it was real 
or not, but you are much more in tune with subtleties of drag than I am, 
so I'll take your word for it (see, that's an example of giving credit 
where credit is due).  So, I'll just assume the difference I perceived 
was psychosematic.  Unless, of course, you've never tried bongdage wings, 
in which case you wouldn't know what you are talking about, and you would 
be as much full of shit as I am.
