I have a 2 1/2" PRC Sprite, 1/4 hollow, 6/8. I only shave around my neck below my beard, and it is perfect for my use. I am able to get into tighter places, and I haven't managed to roll the edge or other wise damage good merchandise. I still have the wants, but not the need for one of those 7/8 or 8/8 razors, but that probably speaks to other issues I have...If it shaves, use it. If it doesn't find something that does. This is far from an exact science, but fun to try things out.
