Well that's why you use pocket protectors Carl! :)
I've been using fountain pens since I got my first one as a present in 1982. I still use that pen (a Sheaffer) when I give lectures and I'm happy to say there's a small but dedicated little group of math-geek graduates who now think the only way to do math is with a fountain pen :)
I picked up a Lamy a few years back and put an italic nib on it which makes it fun to use. A good every day pen.
I cannot remember all the different ones I have, but the ones I like using the most are the Sheaffer, the Lamy, and when I am in meetings with people who are impressed with ostentatious display, my Mont Blanc (I usually take that one along to meetings with Vice Chancellors etc.). As soon as certain people see that star in the cap they think I am rich and conservative, which puts me at the advantage straight away. :)
