I do the pigtails for the hots, but the single wire for the EGC's.
In truth we dont wire house's...however we have one going on now for a friend. It's a smaller home....I didnt use any Multiwire circuits as I didnt want any problems with AFCI issues in the end.....However, I've pigtailing everthing, and used my "greenies" like a good boy....even though it wont be inspected.....
As for the pigtails, I make them up, roll them back,lay the roll over, and gently stuff with the butt of my hammer with my other hand on the back of the box. I dont like rockers chewing up my wires...
