The orifice size has to be the same size as the smallest orifice in the system, gases decompress evenly so trip will be the same whatever hole you open although you will open the IT port, and delivery to the furthest point will be the same as the water pushes the air ahead of it. You will get a little friction loss in the IT line if it's smaller than a larger branch line if it's smaller but for how many feet? Significant?
