copper vs pvc compressor lines?

Sunbelt rentals rents a power pipe threader for $36 day. Bet you could lay your whole shop out and thread everything in a hour or two. I would run all main lines in 3/4. not that much more expensive and you might want to use a sandblaster or big impact some day. My 1" is an air hog and the air hogs or DA's use a lot of air also
