Copper inner stem is awesome!
I've got one. Copper is used for heatsinks and cooling components on computer parts because it is very good at dispersing heat.
Me and a friend have tested this side-by-side with two KM's, his with a steel stem, mine copper. Mine smoked noticeably cooler.
The downstem will take minor dings rather easily, but other than that it won't make a difference.
Also, the copper oxidation may turn the water a greenish color the first few times you use it. It's nothing to worry about and it does go away.
