I own a Phileas, which is a nice writer, but a bit rigid. I also have a vintage Waterman (says Ideal and 14 ct on the nib), which is a bit more flexible. That makes it a bit harder to write with, but also more interesting. Now, I have been looking at a Carene, and would like to know how flexible the nib is.
Btw, visited my local pen store here in Copenhagen, just to check out their stock and prices. I am NOT going to shop there - 375$ for a Carene. I can get them for around 150$ brand new on Ebay. I know that it is not completely fair to compare prices between webshops and brick and mortar establishments, but still. I also tried out a MontBlanc Legrand, which was quite nice - 890$ . Bet you can get that cheaper elsewhere too.
