Having spent years as a Draughtswoman, ink in all it's forms is a very familiar medium and one I'm always happy to work with, especially for detailed ink drawing and brush work.
I use many inks including Indian ink with a dip pen. For a technical pen and ruling pen I use Pelikan Drawing Ink A this was the 'best standard' of ink for many drawing officeswhere the work was an archival nature. All inks will work with a dip pen nib, sable and signwriting brushes, Drawing Ink A is my ink of choice.
A dip pen nib is often the only suitable nib for some inks, especially iron gall ink.
A Gillott 303 dip pen nib and Pelikan Drawing Ink A for this quick drawing on Watercolour paper. Executed using simple pen strokes the spacing between the strokes giving the shading.

A Pen Wipe is the best, simple piece of equipment, for working with dip pen nibs.
Ink in a technical pen, using a pointillism technique on HP paper. Part of an 8" x 10" picture. The space between the dots gives the light and shade to the drawing, this can also be acheived by the size of the dots.
