I agree completely. But when you are trained, and have only worked at one company, if you are taught the wrong way, that's how you do it because you don't know any different. And it's acceptable until there is an incident. I have no problem laying a phase on the arm at all. (with a gut) but we used to use slings as our isolators (or wrap a hoist line directly around the arm) and didn't know any different. I always thought in my head it wasn't quite right, but now I know its not. Good discussion.
