A couple of points regarding pony bottles:
1. Pony bottles are good choice for open water dives (as opposed to
technical dives) especially when traveling out of the country. Most
resorts don't offer tanks larger than an 80, and I can't remember a
resort that offered "H" or "Y" valves. I always make it a habit of
diving with some form of redundancy, and in the Caribbean it's a 13
cuft. pony. In addition to the pony being my own back up, if someone
else runs out of air, I know I can make it to the surface on my pony,
which will allows the panicked out of air diver to have all the air
that remains in my tank as we go up.
2. If you have a problem with balance with the pony bottle mounted on
the right side of your tank, simply put a dive weight opposite the
pony on the other side of the tank. No big deal. My pony in this type
of diving, is nothing more than a spare tire. I would only use it in
an emergency and don't count it's air in my gas management plan.
3. Unless you have very low gas consumption, I would recommend a pony
of 25% of the main tank capacity. If you travel and see mostly 80's,
then a 19 cuft. pony is generally a good choice.
PLEASE NOTE: I am in no way recommending a pony for the over head
environment. It's just to give you some redundancy on open water
dives down to 130'.

The world contains but three types of people:
1. Those who make things happen.
2. Those who watch things happen.
3. Those who wonder what happened.
