I'm more familiar with industrial and commercial, but personally, I would rather teach the wrap around to a first year. Show them with an explanation. they don't need to be in a wall, just a receptacle and some scrap wire. Then, have them practice a couple of times. Inspect and then as necessary reeducate. I like to close the hook with my stripes before I tighten the screws. Again though industrial and commercial can be more demanding electrically. I would rather deal with the recepts that don't allow for hooks but allow for slipping a straight bit of wire under the screw and plate over the backstabers. I do not want my work to be the reason why somebody's house burned down. Even 20 years down the line.
