Author of the post here, I use pencil because it's easier for me. Pens work fine (and I've used pens some days) but I mostly use pencil because I prefer pencil. I have a mechanical pencil that I've been getting a lot of mileage out of.

I found some Japanese erasable pens (frixion) at my local Daiso and fell in love with them. .7 and .5 mm tips.
