Just wanted to share a mind blowing revelation I had with the smoothing settings in photoshop. I always avoided it because I was a dumb ass "purist" and wanted to draw my lines without any handicap, but I was experimenting trying to get my digital work flow closer to my trad workflow and bumping up the smoothing to around 27ish% is like the golden ratio to give it just the right amount of "drag" to mimic how a pencil or pen feels on paper. It comes in real handy especially if you use a screenless like me. If you've always avoided it, I highly recommend giving it a try.
