As a noob, I have been doing quite a bit of reading (here and elsewhere) about brushes. Much like wines, blades and cars, there are an innumerable quantity of attributes. I can't quite drill down to the direction I've taken in personal preference. Many posts are helpful, but I'm looking for a synthetic. So, I'll ask for a bit of help in recommending a brush and keep my preferences simple. Looking for a stiff, dense, non-floppy, scrubby, grind-the-lather-into-the-beard synthetic brush. Not interested in the spreading, painting or splaying type of brush. Really not concerned with whipping the lather or the amount of lather retention by the brush. Sorry if my terminology is sloppy. Still learning. Thanks for your help!
