Mysterious black
I quite like Visconti black, but I can't really say why. It's not too wet and it's not too dry. It's also not the blackest of black blacks, either, shading between a really nice dark grey and black, drying a bit darker. The third black I tried in my Visconti Homo Sapiens -- the only pen I own which practically cries out to be filled with black ink -- and the one that will stick.
