Run the biggest one you can for the main line. It helps slow the air down so moisture settles out and it provides a surge capacity. I would think a minimum of 1/2 inch for branches if they are short and 3/4 inch for anything over 15 feet long. Remember to put drip stubs and drains on the ends of your outlets.
