Most curious: I tried this, Pilot Neox High-Purity Graphite Pencil Lead - 0.5 mm - F lead and the Pilot Neox High-Purity Graphite Pencil Lead - 0.5 mm - HB lead in my Roulette pencil. The "F" lead writes somewhat darker than the HB lead. Hardly what one would expect. I'm going with the "F" lead.

I'm using 0.5 mechanical pencils for about 30 years now and so far this is the very best lead I ever had!
