when i was looking through some of the tanks for sale in on the american sites the other day. i saw that some of the fibre wrapped 68ci tanks were for sale under Co2 useage... i have a shocker which are renowned for poor consumption at the best of times, and as i am now going into the tourney scene and am a back /mid player i need to shoot more than my 20oz permits. So i was wondering.. could i buy an air tank and stick a smart parts co2 valve and anti-syphon on it and just use the extra volume of the 1.1 tank to get me the extra shots i need?
