Has anyone else fallen for the Platinum #3776 Yamanaka with a soft medium nib? It's a beautiful pen to be sure and I do have a fascination with demos. However, in this case, the nib is just as fantastic as the pen. I only had a sample of Platinum Mixable Silky Purple ink, but put it to best use by loading it in the Yamanaka SM. This might just be the smoothest duo in my collection. Call it a controlled glide with a little line variation. Platinum only made a limited number of the Yamanaka SM pens, but I hope the nib appears on more models in future. It's a worthy addition to the line.
