In traffic again on Friday, tried out both the Pilot V5 and the Sharpie Retractable. I preferred the thinner, more delicate line from the Pilot. I wasn't able to get as much detail with the Sharpie which made me draw the vehicles bigger, and I think I lost a lot of the quirkiness I got from the Pilot pen. I think the Sharpie ones look a little boring in comparison. I outlined the Sharpie car with a Medium Sharpie and I don't know if that improved it at all.
