I have a budget of 35 dollars, going to buy from yaqi aliexpress. The silvertip and two band pretty much the same price, just want to know which one should i get.
Pffft, budgets. So outdated... Get both and enjoy. Life is too short!
Our biggest regrets are for the things we haven't done. $35 doesn't buy you much these days, but a good quality badger brush will bring you joy for a loong time.
It's hard to go wrong, IMHO. Also, consider the size. My 24mm Two-band Mysterious Space is an excellent brush. I like the Two-band for a bit firmer feel. Scrubby, but not at all harsh.
I'd consider the Sagrada Familia Two-band 22mm for a slightly smaller form factor. If you like the larger knots, the 24mm Two-band in handle of your choice would be a good one.
For a all around good brush I would choose a 24 mm 2band badger from Yaqi Mountain lake handle or 2band barber pole handle. In Silvertip a 3band 24mm in the "Mysterious space or artic sky" handles. I have 10 different Yaqi badgers and all of them are unique and a joy to use.
The 2band badgers give a nice scrub and are great lather painters, Silvertip are gentler scrub and are excellent lather painters.
Just to be a little more clear, the Yaqi brushes seem a little larger than their nominal size. When the 24mm badger knot fans out with use, it will feel more like a 26mm knot. If you got a 26mm knot, it will become enormous after some use.
