I'm attempting to upgrade my brush from a Vulfix pure badger brush which is....meh. It's a good starter brush, but I've found the handle to be too short for bowl lathering and my hands. Needless to say, there are more than a couple brushes out there, so in an attempt to understand what I'm actually looking for in a brush, what makes a brush a better face latherer than bowl latherer and vice versa? From knot size, to overall height to type of hair, or anything i might not even know about yet, what say you?
