copper vs pvc compressor lines?

I am really lookin at that kit too. I like it a lot. I would want the 3/4" I think though, because I have my media blaster on that compressor and if I do any painting, it will also be done on that compressor. The small portable I have only has a 30 gallon tank and that's not enough volume. My big compressor is a 120 gallon tank.

I always run 3/4" myself since I end up branching off and running air lines everywhere because I want the least amount of hose possible laying in the floor. When I do mine this time there will even be a line attached to the lift. I am doing the same thing with my electric.
