Amen.I've had my SOC Mistura in Taj resin since February of 2019. I used it exclusively for a couple of months when I got it and in frequent rotation ever since. I'm sure I have 150 or so shaves on it. Here's the best I can do in terms of general impressions of its journey in my den:
Shaves 1-5 - Makes and releases plenty of lather, but a tiny hint of scritch along the lines of a brand new Shavemac Finest
Shaves 6-20 - Still makes and releases huge volumes of lather, and all scritch slips away gradually, as it does with a new Shavemac Finest; however, this thing has more density and backbone than my Shavemac Finests and approximates the best versions of Simpson Best I have encountered (including my old Somerset Polo, to which this very favorably compares). Sometimes the glue bump annoys me.
Shaves 21ff - I know exactly what I'm getting every day: no scritch; good backbone; huge lather; easy lather release; ergonomic handle. It hasn't changed much at all after that first month, but I've gotten to know it and do not find any trouble with the glue bump (in fact, I think it helps a bit with lather release). It feels like a Simpson Better Than Best.
Actually, that's damning it with comparisons. It is its own thing. The boar bristles have more presence than Best Badger. The backbone doesn't come via extra density, so there's never water or have-formed lather trapped in the heart of the knot.
It is, for my tastes, the best brush I've ever used. The only thing that comes close is the Torga C3 Mistura, which may indeed surpass it after I know that one better. I've had short-term brush fixations over and over again, only to find that after a while there's some flaw or annoyance that ruins a brush for me. The SOC Mistura, on the other hand, has remained my favorite brush for the entire time I've owned it.
