I impulse bought a Pilot Metropolitan (F) about a month ago and have had the worst experience so far. First it took 3 days of experimenting (squeezing the cartridge, flushing, cleaning, shaking, incessant scribbling) to get it to write at all. Then I noticed the nib was a bit off-center in the feed so I aligned it and it wrote pretty well for a while. This morning I grabbed it to take some notes and it won't start, even after a flush with water and re-seating the cartridge. This isn't my first fountain pen (not even my first Pilot!) but I'm really disappointed because the Metro seems to be such a popular recommendation as a solid, inexpensive starter pen. Did I get a dud?
I do rotate slightly when I write and I have had other pens snag on paper before but I don't think that's the case here. There were no issues with the nib that I could spot other than it being crooked in the feed.
The Kakuno is one of my favorite pens! I've owned several but I wish they were a little sturdier... every one I've owned has cracked eventually (cap, body, or both) no matter how carefully I handle it.
I believe the Metropolitan and the Kakuno use the same nib. So if you like the Kakuno nib and are just looking for a more substantial body, the Metro should be a great fit. Pilot is know for good quality control, but it does sound like maybe you got a dud.
