I went out with a nice Pelian 605 blue with silver trim.
I tested the pen with my own crappy paper against the Pelikan 400 I was carrying, liked the nib and wanted to buy the pen. The salesperson told me, that I would get another, unused pen. I asked her to test the other nib too. She gave me the pen and I did not like the other nib at all. So I asked her to switch the nibs. She could not believe that I asked for a nib various people had used for testing but switched it anyway.
My other Pelikans are 400s so I have to get used to the 605. But I simply could not walk away without the 605 offered for 99 Euros!
