Pony Bottles

Your SAC rate is pretty phenomenal.  28 min on a 13cu ft tank at 55 ft calculates out to 0.174 cuft/min.    Most divers are somewhere between 0.5 at rest and 0.8 while swimming.  Using a typical newer diver rate of 0.8 cuft per min, you would only get just over 6 min at 55 ft using a 13 cuft tank.

I agree, diving is fun but sometimes you like to do more challenging things (deep/cold/wreck penetrations) and for those activities, a pony makes a lot of sense.  I wouldn't put a pony on most newby divers, but as divers get more experience and they get into more difficult situations, a pony may be the right choice.
