Ted-

I have some questions about your back mounting:

-How do you check the pressure of your pony while underwater?
-If you use a gauge, how do you have the gauge rigged?
-How do you keep the bottle and hoses from snagging fishing line, reel 
line, nets, etc.?
-Can you quickly and easily pull it off when you have to while underwater?
-Can you quickly and easily put it back on while underwater?
-How do you check for leaks during the dive?
-If you do the above, how many times during the dive do you check?
-Can you reach the valve?
-Isn't this weight on the side of your tank just one more thing to fall 
off or snag?
-How does this weight account for hydrodynamic drag unbalance?
-What do you say to the diver next to you in the tank rack when you bash 
your pony into his gear?

You might ask these same questions for those who strap a pony between 
your doubles.

Note that none of these questions have to asked for a stage rigged bottle.
