I'm thinking (seriously contemplating) of purchasing a regular size phiniac tank and trying out a couple different types of cartos (boge and kangar horizontal coil). I'm wondering if the height of the carto makes a difference with longevity and chanelling of the juice. Is the height of the system (tank + carto) only a preference for not having to fill as often or does the height of the carto make a difference in any other way that I can't think of right now?
