At this time last year, I was wiring my first building with these things.....
I was very fortunate in that I had an absolutely free hand in deciding what receptacles went where, light placement, etc. I also, unfortunately had absolutely no information as to room layout, equipment location, etc.
This was particularily vexing, as with this type of construction- and unlike regular feaming- there is absolutely NO going back and making changes or additions later on; you pretty much only have one chance to 'get it right.' Once the drywall is up, any changes call for major, and I mean major, work.
I was lucky; my guesses were 98% on the money. The remaining two were- luck again- possible with minor work. (I was able to remove the cove base, rout a slot for the wires, and re-cover. The MC used was also protected by a length of steel channel).
