Today I just purchased two 13.2 gal kegs and one 15.5 gal keg. Any suggestion how I should set them up? My plan was to use the 15.5 as the MLT and the 13.2's as the HLT and kettle. I would like to brew 10 gal batches down the road but would I be able to boil a 10 gal batch with a 13.2 gal kettle? I am not worried about the HLT. Is the extra 2.3 gal more important for me in the MLT or the boil kettle?
