My lines are around 5ft long and I had my PSI set to 12 for quite a while. After numerous over carbonated beers, I did some research and found that 6 PSI would give me around 2.5 vols, which is what I was shooting for. My question is that is there any advantage to the more common 10ft line and 12 PSI set up? To me, saving money on shorter lines and less Co2 seems like the logical choice. Am I missing anything?
