I've also ascended with nine of the twelve official conducts (not all at once!) in 3.4.3. The conducts I haven't attempted (and doubt that I will anytime soon) are illiterate, foodless, and pacifist. My best behaving win to date was a six-conduct Monk (vegan, vegetarian, weaponless, artifact-wishless, polyselfless, polypileless). I nearly always try for artifact-wishless and polyselfless conducts, only breaking the former to wish for Grayswandir in an atheist ascension.
On June 28, 2016, I achieved my goal of ascending with all 38 possible combinations of role, race, and alignment. See my NAO dashboard (does not show the conducts that I achieved before NAO got xlogfile installed after the Great Crash of 2008, including that six-conduct Monk, atheist and genocideless Priestesses).
I've been playing Nethack since 1993, version 3.1. My favorite role is the Priestess. (I almost always play female characters, solely so that I can lay eggs if I step on a polytrap before acquiring magic resistance and happen to get polymorphed into a useful form.)
In real life I am a freelance photographer and blogger, living in San Francisco.
