. . .hard to argue with any of those. If you don't feel like fooling with a piston filler in the middle of a meeting may I suggest a later, cartridge fill 51 or cartridge fill 75- extremely reliable workhorse pens both that won't call attention to themselves unduly or be so labor intensive as to be more of a hindrance than a help in a meeting. I personally would go for a 75 or Sonnet (another great writer) with a matching ballpoint backup. I use my 149 for grading final exams but not much for serious note-taking; it's a great sketch pen too, by the way. The Pelikan is a good compromise between the 149 and the smaller pens on your list, with great construction and quality, but as it's a piston filler it might lose points from a pure high volume, practical writing standpoint. Writes on the wet side too, and the fact that the wet line takes longer to dry can produce annoying smears not only on your notes but your shirt cuffs
