Do these little tanks have liquid co2, just like their larger counterparts? If so, then couldn't larger tank setups theoretically use similar setups due to similar pressures? It might be beneficial for any of these setups to get a needle valve that is actually rated for the about 850 psi that co2 cannisters with liquid usually have. I called up a few needle valve companies; one guy said I couldn't do it, another said that it's possible, but the co2 output wouldn't be consistent. Sounds like dolla is already manually adjusting output and this isn't too time intensive. Does anyone have thoughts on this?
