Well my M6 arrived last week and my first impressions a very pretty looking brush indeed beautiful variations of colour in the faux horn handle, I've used the brush three times with hard soaps it's perfect for them even with the relatively small knot there's lots of backbone not as soft as say my Simpsons P8 in best but I do expect the brush to slightly soften after 20 or 30 shaves, overall feeling yeah I like the brush and I'm pleased I made the purchase.
Those post bloom pics make the brush look way better than some of the others I have seen. Nice brush, and congrats on scoring one.
