Totally agree. I used a fountain pen all the way through school and university.
My all time favourite was the Parker 25 in stainless steel, with a medium nib and blue-black ink. Sometimes I would go for purple if I was feeling a bit raunchy.
I know a lot of people liked the 105, and I had one, and a bunch of others, but there is something about the utilitarian functionality of the 25 that I really have a soft spot for.
I think there was a year or two where I may have flirted with ballpens, but not seriously.
Also even used Rotring and Staedtler Mars technical drawing pens on and off for regular writing. That was always fun in the middle of a lecture with ink everywhere.
It's such a shame I don't get to write on paper that much these days. No real need. Such a beautiful experience though.
