I like my 7/8 razors for the ease of use. I have thick hands and fingers; griping and using a larger blade is easier than a small blade for me. I have 21 razors in my rotation ranging from 4/8 to 7/8 and as far as their ability to get the job done there is no difference, it is just how they feel in the hand. As for not having to wipe the blade as often I personally find this to be untrue until I get out my 4/8 J.R. Torrey; I shave in sections (right cheek and hand then left cheek and hand ect.) and wipe between each out of necessity so a 5/8 holds all the lather I can get on a section of face.

Now my wife is going to be mad at you for agitating my RAD by reminding me that not all 21 of my razors are 7/8 or larger. I am off to look for another 7/8 C.F. Wolfertz, I would try and find another large W&B but Phrank bought them all. Anyway that's my two cents and as always YMMV.
