I’d say this?
I have a Semogue 2015 HD - 22 mm high density 2-band finest. Terrific smaller brush. I have a hunch that that HD version may be too much hair for you. With the caveat, that I don’t have (the not high density) 2015, I have a hunch that the 2015 may just be your brush.
These sound like very nice brushes if either could be purchased for under $30 (which is one of the OP's criteria).The Simpsons Berkeley 46 in best sounds right up your street.
How often are you shaving? Daily? Because unless you are going days between shaves, the idea that you need to "lift" your beard hairs to hydrate your stubble is a shaving myth....felt like all it was doing was painting lather over my beard growth (my beard grows very parallel to my skin and I don't think the Yaqi was firm enough to lift the hairs to lay down some lather for the hair to lay on, if that makes sense.
It's common that manufacturers often don't give their suppliers the knot size, in which case the supplier usually measures the knot diameter at the top of the handle. The supplier then states their measurement of the knot diameter... which it isn't. In general the knot diameter is ~2mm smaller than the hole in the brush handle.I'm really liking the look of the specs on the Omega 10015, but I'm noticing a discrepancy. On the thread that lists all omega knots by size states that the 10015 is a 20mm knot.
However multiple vendors, fendrihan.com for example, lists it as a 22mm. Can anybody verify either way?
The reason I asked Jim to comment on the Mixed Midget is that he's used his recently. I checked and it's been 2½ years since I used mine! So, naturally, I had to take it out of retirement and have a shave:
