I have a Rockwell 6C (Gunmetal) and am using it with Feather blades on setting 5 or 6. I have a bit of trouble shaving under my nose, also the corners of my mouth. Thinking it is because the 6C has quite a bulky head, and I am wondering if I would fare any better with a Game Changer .84? Some reviews (comparisons) seem to suggest I would. What do those who use both think?
