I'm going to be buying a Pelikan M1000 in the next few days and was wondering what Nib size to order. I currently have an M805 with a B stub nib that I love. However, I had an M805 with an F nib that I preferred slightly more and my current daily driver is a Lamy 2000 with a M nib. Having used the B and F nibs on the M805 extensively, I'm leaning towards an F nib on the M1000 but I've also heard that you start to appreciate B nibs on fountain pens after writing with them for a while. Which nib size would be a good choice for everyday writing?
I'm also debating between color choices and it's come down to either the new M1005 with grey stripes, the M1000 with green stripes, and the all black M1000. I'm leaning towards the all black M1000 due to the fact that I find it hard to see the ink level through the stripes of my M805 but I'd also like to have stripes because it's Pelikan's quintessential design. Is the ink window good enough to justify getting the all-black pelikan (I haven't seen much about the ink window) or should I go with the stripes and if so, which color? Thanks!
