I am fairly new to this I have full hollow that is a 5/8 and another that is 6/8 the 5/8 is very flexible while the 6/8 is not. Both are very nice. In my personal limited experience, angle is important to whisking off the wiskers, but if the razor is bending on your face you are probably pushing too hard. Get the correct angle and a sharp blade and you will not need any pressure. Go with the hollow!
