What is a collection? Lamy Safari Update

Clockwise:
Visa (F); 2009 Orange (1.1); Yellow (1.1); Red (1.5); Blue (F); Charcoal (B); Lime (1.1); White (B)

Since posting about my Lamy Safari's here, I've traded, sold, given away and reconverted my stash of these colourful pens.

Here's the latest hoard.

Still unsettled about the Red 1.5--too wide even for me.
