The Pilot S20 is beautifully proportioned and balanced. If you are comfortable
writing with a slim profile ballpoint, this is a good workhorse for every day
use. My reason for awarding four stars and not five? The ink tended to build up
on the tip during extended use and I had to wipe it several times on a scrap
piece of paper. Perhaps Pilot recognized this and reformulated the ink in the
recent past...I have no way of knowing unless I buy another S20 because I gave
mine away to an admiring colleague some time ago!
