I currently own an Omega 10066 and after ~30 shaves with it, I still find that I don't really care for this brush. It seems really sparse compared to my Plisson Synthetic and EJ Best Badger. It doesn't seem to hold lather very well at all, which I think is due to how few bristles are actually in the knot. I've been considering either a Semogue 620 or 830, but I'm having a horrible time trying to choose which one to get. I face lather exclusively and have extremely dense, coarse hair (we're talking rebar). Everything I've read has said that the 620 is much better for face lathering, however I also hear complaints about it not holding much lather (similar to my Omega) and also being a bit scratchy. I hear great things about the 830 being good for both face and bowl lathering, but people say it gets too floppy once broken in and becomes bad for face lathering at that point. Does anyone have any experience with these brushes? Can you please help me decide?
