Fitting a High capacity tank on the A-5

Lets face it; the A-5 is my baby. I love it. BUT, the thing does have the tendancy to eat through CO2 faster than I like changing tanks. Especially on those 12-24 hour scenario games that I love so much.

While at the OK DDay this past year, I noticed someone who had come up with a solution to this: a high capacity CO2 tank, supposedly purchased from a Beverage Supply Company (Kegs of ber need massive amounts of the stuff.) The player had mounted the tank to his back and ran a remote system. You'd never have to fill up that way, and you'd be good to go.

My question is: has any one done this, experimented, found any pitfalls or shortcuts that I might be able to use? Any thoughts on the subject as a whole?

I was thinking of an Alluminum tank simular to this, in the 5lb  variety.

Who  can help me out?

Thanks guys,

Either carry an extra 20 oz on you(put a thread saver on it)
or
Buy a huge HPA tank. Something like a 114/4500

or you could get one of those huge tanks used to fill other tanks and push it around in a wheelbarrow, which can double as a portable bunker

or when you go buy your next case
