I like the flat grind better myself. In spite of the excellent blades that Bob Loveless ground, I think the hollow grind is a bit more fragile. Possibly because my 8" wheel was too small for the width of the blade I was grinding, I managed to get a nice looking blade that snapped in half when I tried flexing it. Looking at the cross section of the blade, it was much too thin in the middle - like a straight razor. Great for shaving, but not much use in the field. I find the flat grind more visually appealing, but also much easier to control.
