Justincaseme,
"So tell me more about this marvelous Klein device for my left hand. A google search brings up quite a few Klein tools and I'm not sure which you mean".

I appologize, some local Electricians have Kleins, I have Mostly Klein Tools for Electrical, But when anyone says a pair of Kleins, they usually mean these:

If connecting several wires, I will strip back about 3/4-1", twist with my Kleins in my Right Hand(I'm right handed)South Paw woud use left to hold their Kleins, and wires in their right hand. I twist all tight with Kleins, cut square off, then wirenut.
Like I was saying about the photo, The wirenut appears like he is about to turn counterclockwise, and not twisting wires tight, relying on wirenut for strength?
Another stupid thing I feel is he is just now making up the grounds, a switch and receptacle is already in place.
Personally I make up grounds in a switch box, tuck them away, then the neutrals, you are left with hot and switchlegs, connect to switches.
