Well that settles it then. No, really, I appreciate all the input. I suspect both ways would work. The funny things is I have a couple of partial rolls of soft copper. I have had it for a decade. Makes sense to use it. Ahhh, but the rub maybe that I want to get off to a good start with this tech. who suggested the black pipe and left a good impression of himself. The other two that came out months ago never called back as they said they would. My thought was that those other mobile guys didn't want to get down and work. They wanted to make there money running around around the job looking at the job ordering parts and picking them up and then oh darn I guess we have to install them. So when a man comes out and ready to roll up his sleeves and get it done -- well I want to get off on the right foot with him. I want to vet his suggestion but if at all possible go with it if it makes sense.
