I love my Diamond, but it's a bit back heavy for me. And to me, the 2000 looks a bit more avant garde, and I've heard awesome things about the nib, so I'm willing to overlook the hood :) I can definitely recommend some inks if you want!!
I'd love to hear your ink recommendations. If I was to buy an ink, it would be either a pearly black or a a dark blue (maybe with a bit of grey.) In fact, a nice grey ink such as the J. Herbin would also be awesome. It would need to be better than standard cartridge ink to write with if I were to buy it, and I'd like an ink that is clearly different to your average 'biro blue' or 'ballpoint black'.
Is it back heavy with the cap posted, or is it the pen body itself? I've been mulling over getting one for my spouse. The Diamond seems like it'd make a good gift while also possibly infecting her with a pen habbit. She has short fingers though, and if it's balanced weird... might not be the best introduction?
