How do you know it's the 0.9mm italic? Doesn't say so on Massdrop's site.
And for those who don't normally post when writing, these are intended to be posted -- the threads on the back end of the barrel are there to fit the threads in the cap.
Before the drop was set up, there were votes on color and on the nib. One of the nibs on which one could vote was a 0.9mm italic. And I also recall from perusing online vendors who carried the Passaporto in recent years, the only italic nib offered was a 0.9mm one.
I think BarkingPig's points in a previous reply are very much to the point. Pocket pens like the Passaporto, the Franklin-Christoph Model 40P and the Kaweco Sport are special purpose pens. While they have some criteria for "goodness" in common with "ordinary" pens, they have other criteria that are unique to their special purpose. One is small size when capped. One way to be small enough to carry comfortably in a pants pocket and still be long enough to write with comfortably is to optimize balance for posting.
I also prefer largish pens like a MB146 or Pelikan M800, but I don't carry those pens in my pants pockets.
