I generally use a Pentel RSVP for spinning...turns out it also makes a great sketching pen because of the pressure sensitivity. Most comfortable pen to write with has to be the Papermate Profile - the ink is soo smooth. The Pilot Easytouch has great, consistant and precise ink but it can feel a little bit scratchy. I don't like gel pens like G2's or Signos because they all tend to be a bit scratchy and ink bleeds sometimes.
