Sparky,
Why are you working things hot? I can think of very few good reasons to do anything hot.
I prefer to use Buchannon wire nuts & they include a nut runner in their bulk packs, it usually ends up twisting the wires, but even if I did the connection manually, I still wouldn't twist the wires.
Personally, I think that the twisting is a carry over from the days of soldered connections.
