Retro51 The Odyssey Tornado™ Rollerball Pen

I only write with fountain pens, and really wanted this to be a fountain pen. However, as a classics teacher the graphics were too good to pass up. The confrontation with Polyphemus (who appears to have flying sheep!) and Scylla (with serpentine instead of the correct canine) heads are good, but the selling point was getting the sirens correct - Greek Sirens are *not* mermaids and the artist made them splendid avian-human hybrids as did the myth. Will I write with this? I'm torn between holding out for fountain pens and using this work of art. If you must write with a roller ball, Retro 51 makes ones less horrid than most.
