@c7488e20 These are the ones I use as well, although I only have size 2, 1 and 0. I find the brush tip enough for the details I need.
@8bed88ae you can most things with just the 2,1 and 0. I use the smaller ones for more specific jobs, the 0/2 and 0/3 are almost completely interchangeable, but the 0/10 is useful for those really fine details (like the eyes on a Hobbit)
