A little while back I made a purchase from Jetpens.com for one of their brush pen sampler sets and after receiving it I did a bunch of tests to see what the capabilities were, -which ones could produce the thinnest lines, the thickest, which ones smudged, which ones reacted well to markers, etc. I also did some inking pictures and this guy appeared in one and just got more and more textured as I played around with the pens.
