Are both your safari pens fine nibs? The pen I have now has a medium nib, I was actually looking to buy a fine nib. But I definitely don't want that scrubby feeling
If you want a fine nib that's still pretty smooth, you might want to take a look at a Pilot Metropolitan. A Pilot fine will usually lay down a thinner line than a Lamy fine.
All my Safaris have a fine nib. I do not find them scratchy or scrubby. I do find the medium nib too broad for my liking.
I got a gift from my parents; a bottle of Standardgraph Lilac ink, and a bottle of Pelikan 4001 blue black The Standardgraph ink is hard to get outside Germany.
