I joined the ranks of Conway Stewart users the other day when I received my new CS 100 with medium nib. It's a great pen - a very smooth writer directly out of the box. I am very impressed with the quality and beauty of the pen. I would have to admit that it is the best writer that I have. It puts down a nice line, a little on the wet side, with almost no pressure required. I haven't detected any trace of skipping or delay in starting. The color of the pen is Sepia Blue - a little darker than I had anticipated from the various photos I had seen on the internet. The color does look different under different lighting conditions. Under sunlight the colors reveal themselves in a bright display of blues and browns of various shades. In more subdued lighting the pen looks like a dark pen of little color - very classy.
Does anyone know if Sepia Blue is the same color as Burnt Umber? The descriptions and some photos appear the same, but I was just wondering.
Anyway, I think I will stay with Conway Stewart for a long time, especially since they offer that special order (Bespoke) service.
Edited to change "Sepia Brown" to "Sepia Blue" as pointed out below
