I picked a bottle of this from the traveling ink box. I also have Waterman (Havana) Absolute Brown. The Waterman does not flow as freely as the Visconti imho; the colors are almost the same too. I will be choosing the Visconti over the Waterman if I buy more brown ink.
Visconti gets lost in the ink market but I have found their inks to be exceptional. If you wish to have a lighter shade of brown check out their sepia. That ink is awesome with great flow and excellent shading.
