Any opinions on the Dia II. It looks interesting to me, and my wife is asking what I'll be wanting for my birthday in a few weeks. The price seems a little steep for a converter pen, but a converter pen can be perfectly as well made as anything else can be. Do the nibs run fine or broad for their size? I write with Pelikan "F" nibs, which I find to be kind of a medium-fine level, which is what I like. Any opinions on the trim - gold versus chrome in terms of quality and appearance?
