I thought the reason for black iron was the condensing capability of the 
pipe, no?

Like you, I think that the threading, cutting, and sealing issues with 
black iron are a huge pita, and copper is comparatively cake to 
install.  But if black iron is that much better at keeping the air dry, 
well, I'm only going to do this once...

What say the list?  Am I overstating the benefits of iron?  Something 
else to think about is that copper won't rust on the inside.  There's 
that...
