51
L-R:
- Platinum Prefounte (M)
- Montblanc 146 (M)
- Pilot Capless Decimo (M)
- Hero 330 (Parker 51 demi clone) from circa 2000 with a 1.3-ish stub I ground myself back in the day as a college student with a dremel and wet-dry sandpaper. Actually writes like a dream as long as you keep it in its sweet spot
- Lamy Safari Demonstrator with knockoff 1.1 stub (wife bought me two of them a couple of years apart, so the second one got the experiment)
Which one do you find yourself using the most?
I accidentally responded to your comment under the other one, so you can check it there, but the short version is that these are only what's been in rotation recently, but the Hero is the overall leader due to age, and the MB has been the more recent favorite.
