3/16" vs 1/4" beverage tubing. Are there pros and cons for each? does it even matter???
which one is better!!!
which one is better!!!

Use 3/16" Beverage Tubing - unless you have a very long run from your kegs to your taps (over 15 feet).
I think you need to do a little digging for information on balancing a draft system. There is a lot of misinformation out there about setting up a balanced system. You might be interested in reading this document that was written by the inventor of the forward seal faucets, Brad Amadzich: How I can get a better pour out of my Kegerator?
I firmly belive it's worth the read.
I hope it helps.

I too am confused because I can by a manifold with 1/4 or 3/8 barbs.....which should I go with? It will be a standard old fridge with the co2 outside the fridge, not traveling far. here is a pic
