Finishing up my brewstand frame and am ready to move on to the gas....Is there any reason not to use 1/4" black pipe for the propane manifold? It seems most people are using 1/2" and extra reducers/fittings to get to the orifices. I have a BG14 and 2 BG-12s and I am thinking only two at a time would be in use, will be using high pressure and have a 0-30psi regulator. Am I missing something??
