I recently switched to a fountain pen - way easier to write with and way less tension. Neil Gaiman suggested it and so I gave it a shot. Never going back - my handwriting is better (but I write cursive) and it is easier to write longer without strain. That said - super cool story.
You can certainly go deep with ink and pens and whatnot, but you can buy a Lamy for cheap on Amazon and just stick with cartridges and still get a far superior result.
If anyone feel like their writing is sloppy and avoid writing because of it, try a fountain pen.
