Jerry I do like your way and often does it like this. The only thing I can think to add to the good Technic is: make sure not to have any strand of wire or pointy sticking out that may come through the shirk tube and cause a short or a breach in the insulation.
On an other note, while talking about wire, do not pick through the wire with the test light, always test at connections, SPECIALLY if you live in the salt belt. I've seen more than my share of trouble cause by shade tree mechanics causing more problems to electrical wiring than I can care for.
