Just wandered if anyone has any suggestions I am currently happily running a kraken rba and wanted to know if there is any alternative that would work nice on a ego battery I want an alternative to take on my hols but don't want to take my kraken. I have a mini pro tank 3 and a mini aero tank but feel unsatisfied with the vapour production. I know the new kanger sub tank is out and the atlantis but they are big tanks and was looking for something a little smaller and less conspicuous!!!
