For me, much as Flyin' Dutch said at the outset, it's a combination method for a visual approach. I don't analyze it too much, I'm not an instructor, but I would guess that the majority of the time it's ROD with elevator, and speed with throttle.
On the ILS its ROD with elevator and speed with throttle - though again, I think that for me too much analysis would get in the way. I would rather find an instinctive method which gets me in a suitable place, at a suitable attitude, and at the right speeds.
