Last night I took notes at a FEMA meeting with both. One thing Palomino has down pat is laying down a dark line. When the PBW602 first hit the paper, I thought, oh, this is smooth. The slightly larger circumference makes me not mind the hex. The point lasted longer than the Original, in this unscientific, fast scribbling notes at a meeting, test. Then I had to change to a Biro because I forgot my sharpener. oy.
So, there you have it. PBW602, a very nice pencil. The difference in the smoothest between it and the Original, while there, is negligible.
Oh, and I heard everything the FEMA guy said. ; )
