im acquiring a new razor for myself. i want to go up to 7/8.

i've seen lynn talk about how he likes 1/2 hollow grinds
and others like extra hollow grinds.

my question is, at 7/8" i would think a full hollow would be the sharpest because of the big blade size, it has more room to come together to a point at the blade. am i wrong in thinking this?
