Well one person asked and I have only been str8 shaving about 2 months. I started out with a 5/8 hollow grind and now that others have mentioned it I did notice it is not as forgiving as my larger blade which I believe is closer to a wedge then hollow. I do not find it any harder to shave under my nose with my 7/8 no more then my 4/8 or 5/8. I think starting out with the hollow grind though may have forced me to get the technique down quicker as it is not a forgiving razor.
