I do. It's not high quality.
As for the recommendation, I can't give you one without knowing exactly how much depth you have to play with. Since I'm assuming very little, I would recommend only the D01 two-band from Shavemac. It's unlike any other knot out there. You can't even compare it to the Shavemac knot you have now.
You will need that incredible backbone to keep it from becoming a floppy mess, but will still get soft tips. Setting it that high in the handle will probably result in a brush that has slightly more backbone than a regular finest/best knot from (insert generic high quality manufacturers here).
The D01, when set at Berndt's preferred setting, feels like a fuzzy eraser for at least a month of abusive use. It's a right love-child to break in. I had mine reset a few mm higher in a different handle, and it made a world of difference, but still has more backbone than any other brush I've used, and I've used many brushes.
