I strip the jacket, twist the bare grounds and install a "greenie" and roll up the wires real good and as far back in the box as possible to avoid the rotozip bit. When it's time for pluggin' and switchin' it goes real fast. If it's a GFCI that feeds down stream receptacles I strip about 1/2" off of the ends of the "line" pair in the box. I do the same thing to the home run in the first receptacle box it hits. I also mark the floor in front of the home run boxes with red paint in case the GC needs an outlet heated up early for lights or a heater to help dry the mud.
