Based on our conversation, I did some comparing and took a couple of admittedly low quality photos. The nibs and feeds I opted to compare are raided from a Pilot Plumix, a Pilot Metropolitan, and a Pilot 78G.
The nibs and feeds are the same shapes and sizes. The 78G nib is gold colored while the others are steel. The feed from the Plumix is black while the others are gray. I tested all three with the same body and section and the same ink.
I added the Lamy 1.1 to the comparison as it has been mentioned earlier in this thread. The 78G broad/stub appears to be about the same size as the 1.1. The Plumix nib is tipped and could be easily used daily writing.
I am a huge fan of these Pilot nibs on a cost to performance basis.
Sorry, no scanner.
