Great to know those options. Coincidentally, I just graduated pre-PA, so I'll have to try the extra fine nib in med school!
I bought the light blue with a Fine nib. It rapidly became one of my go to travel pens. You mentioned you would be afraid to travel with it, but mine has taken a huge beating. It has been to beaches, hikes, camping, sat on, you name it. It is also the first fountain pen I have taken on an airplane that has not leaked. I even left it uncapped once during a flight just to watch it, not even a little ink came out of the nib.
I also liked it because you can replace the nib with a Japanese Extra Fine and medium italic from the Plumix and Penmanship. It was a good intro into those line widths in a much nicer pen than the originals.
As a medical student, I usually need to write in pretty small lines and the F nib wrote beautifully, the perfect width for minute lines. I bought it after a F Pilot Custom 74 and that 74 has remained uninked in a cabinet since (I'll probably be getting rid of it soon).
Anyways, the Prera is a durable, fun, portable pen for a great price (around $30). My wife liked mine so much she bought her own and then proceeded to steal mine and in my book you can't get a better endorsement than that! Congrats on the pen!
