I also used copper, just up one level to Type 'L', in 1/2, 3/4 and 1" sizes with Stay-Brite silver bearing soldered joints. I really like how easy it is to work with and modify as needed. The compressor is at 175 but right after the dryer there is a regulator that drops it to 135 for the copper distribution into the garage and all around the workshop.
