I've got a wee question, what do you use to line your traditional sketches?
These are currently my go-to pens!
Copic Multiliner - Fine nib usually, Brush pen tip is also nice. The ink is water and copic proof, so I trust it to not bleed. I find the tips better feeling and lasting then Microns.
Pilot Precise V5 Extra Fine - My staple "cheap" pen, I buy them by the box. No good for wet media, the ink will bleed. Great for sketching and notes.
Morning Glory Mach 3 - My new love. Incredibly fine line, smooth sketching, holds up to marker and comes in many beautiful colors.
