[RE-wrenches] EMT in attic - vs FMC vs armored cable

[Benn At DayStarSolar]

Sounds like you are referring to what we refer to around here as teck cable. Very common stuff for industrial applications. 
Here,  pretty much any electrical wholesaler has stock in several configurations. 

Can be ordered in 2,3,4,5,6... (Not sure the limit extent) number of conductors and in pretty much any awg size and usually comes with an appropriate sized bond. 

Just have to watch the exposed/visible horizontal runs as it will sag and look sloppy.   
I'm pretty sure I have some spec sheets if you like. Request them offline.

>> This subject interests me as I had been considering using waterproof metallic armored cable. I can get pre-made cable with just about any number of conductors of any size, sheathed in a flexible metallic layer and then a UV resistant waterproof layer. The stuff is direct burial as well. Buying 4 conductor and ground #8 would handle 95% of my residential work. I could overkill with #6, or 6 conductor, and the savings on all the screwing around with conduit would still make it better. In bulk it's actually about the same price per foot as individually purchased wire and conduit.
