Look guys, the whole hogarth idea is for decompression diving. Trying to 
apply decompression gas management principles to NDC diving is a waste of 
time. The only use for a pony is to give you enough air to get from the 
bottom straight to your 3 min. 10' stop. A 15 cu.ft. tank is enough for 
this.

If you are decompression diving, then the solution is a set of doubles, 
and turn at 1/3s. This will give you enough gas for whatever situation 
you might come across. 

To rely on a pony for backup decom gas is as stupid as diving independent 
doubles. An H valve is a halfway measure, does not measure up to doubles 
with a isolator.
