I watched a guy wiring tract homes using boxed Romex. He'd throw a bunch of boxes on the floor at the panel, cut the center out of the box and drag a bunch of home runs across the attic at once. What a mess.
The guy on the posted link is using a ratchet bender. WAY too much work. I used to use one of those and then graduated to a hydraulic fliptop with the hand pump. Still a ton of labor. Finally forked out for the electric pump and things have been great ever since.
The Simpull rep was at our local CED a few days ago with a sample of the wire "reels". It seemed to pull off pretty nice. It comes off without being messy. A manufacturing procedure that they have proprietary rights to. He said the way it is coiled is the kicker to it being better than some of the older systems.
