One thing not mentioned by anyone on this thread - how long a 19 will last also depends on your air consumption rate. If you haven't checked recently, you ought to check what yours is now. That will tell you how long any bottle will last.motorcitydiver:Hey guys thanks for the info. Just like anything else on this site everyone has good pros and cons for every subject. I think I'll try both and see what works best.
in_cavediver:I would recommend slinging on the front, rigged like a stage bottle. My opinion is that this should be treated as a competely independent gas source with the 2nd stage 'stowed'. You should keep the standard 1st + (2) 2nd's on your main tank and keep you standard gas plan. The pony, IMHO, is 'your' personal reserve that your buddy is supposed to be reserving for you.

I agree with everything above but I would loose one of the 2nd stages on the primary because 3 regs are a bit much. If you primary 2nd stage goes bad simply switch to the pony, abort the dive do your safety stop, surface and fix the problem.

That is to say you don't agree with cavediver.
