Just took delivery of this 2012 M605 blue striated to join my 400NN green striated. The nib is an M, which is much fatter and wetter than I'm used to, but I really wanted this particular pen -- an M60x blue striated with rhodium trim. It writes very smoothly with only a touch of feedback. For EDC, though, I am planning to swap in an EF nib as it's just more practical with the common papers I use at work. I really love the look and feel of this pen.
