thanks James - yeah I am considering setting up the mixed gas (Don't shoot me now but..) was thinking of using it not just for stout but also maybe for ales from time to time too, simply because at the demo I went to at the homebrewcompany.ie they had a pale ale going through the nitro too and i thought it was quiet nice - just something I am considering - could be an awful idea - probably just go with the CO2 stuff for now I guess I can always upgrade - extend the system in the future
