One of my old studio mates got rid of a box of old oilsticks. Before recommending to the students that they try to use them for monotype printing, I gave them a quick try. They work pretty good, but still don't give a very fine point or much control. I've still found it's easier to get much detail and depth with reduction (wiping away material with tools) that with the addition step.

I drew the skull without referrence, which explains if not excuses the misproportion.
