It seems folks struggle with heavy grinds. Some do not like them, finding them difficult to wield. Every time a thread like this pops up, standard statements are made that heavier grinds are easier to use or the heavier grind compensates for poor technique. I'm sorry but there is really not a science to any of this. We can make speculations. We can rely on some understanding of basic physics and geometry. We just do not have an hard evidence one way or the other. You can also mention the tools barbers used after the heavier grinds 'disappeared', but the thing is they still kept making them. I think DD made a 'wedge'. Red Imp made a 'wedge'. Besides some of the 'full hollowed' razors back in the day were not the paper thin hollows. I had Torrey razor that was an 'extra full hollow' that honestly looked more like a 1/4 hollow. At any rate, I do not disdain or cannot use full hollow razors. Well, as long as the steel is hard enough I can use them, but I have never fallen in love with one. So I am sure some standard quips will come. Some hidden mystery of straight razor history will be given as proof, but this is not lab. Anyway, sorry for the rant. I tell you what. If we can ever get together, I will bring my one day beard. You can bring your favorite singing follow hollow razor and give me a shave. After all, most of us will only shave our face. How many times can we shave another. So I am willing to put my face and beard under the microscope. Well, not literally, unless, someone does have a microscope handy.
