Yeah, I factored in the height above my keg.
I think I may have screwed up the carbonation level. For this beer, I wanted about 2.4 volumes of CO2 at 39 degrees. Using a few online calculators, it says I need 10.2 PSI. I carbed this thing at 12-13 PSI, and I balanced my system at the 12 PSI level. I'm not sure if this has any effect.
I think I'll order a 10 foot line with my next order, just to try it out. It's going to suck removing the existing line though, it was a tight fit.
