My variety of brushes are mainly during my inking stage; I use Clip Studio, therefore...
Frenden MS4 Flexible nib- this is the brush that I use for the majority of my inking; it flows very nicely for me, and I get a good variety of line widths out of it.
Frenden MS4 Organic brush- I use this as a complimentary brush to the Flexible nib. It's a little stiffer in its flow, but flexible enough to give me some nice lines thinner than what I get with the flexible nib. I use this for thinner quality lines, as well as smaller detail line work.
Inker/flexible nib- kind of the same as the MS4 flexible, but I have the size set pretty low on this one to give me VERY thin lines.
As far as coloring goes, I do most of my coloring in Photoshop(so I use the standard hard/round PS brush for everything as well as paint bucket), but I do use a brush in CSP- texture effect(rough) to create a splotchy/grainy like texture in a lot of my background-less panels and pics; I bump up the shade enough to create a nice texture that subtlely stands out. If I do use other brushes outside of that, they mainly are "effects" brushes.
