I've recently bought new nibs and a brush, here is a try using theses new tools: "try" would be the good word, actually, since theses new nibs, supposed to be better for drawing, didn't worked well so far - i washed them several times, thought.
The brush worked better, just not in the sense i've foreseen: i've watched several artists using brush as a pen, for inking, but in the end, it was incredibly better for inkwash.
