So my beginner brush was the cheap but reliable Tweezerman brush that has a solid following around here, especially for those just starting out. I like that brush, but am looking to get another, mid to high end brush. I always hear about Thaters, so I'm leaning toward one of them, but would like some others' thoughts.
So what say you? What's your preference for a non-beginner brush? Knot size, brand, etc?
