To me half hollow with some heft work best. 13/16 -7/8 with thicker spines fit the bill great for me. Hollow ground 8/8 also fall in my preferred weight range but they are harder to maneuver on some areas of the face. I also appreciate 13/16- 7/8 Japanese frameback razors. They combine the stiffness of a wedge with the thinness of a hollow ground blade.
