Funny, a thread in the THF forum similar to this just apeared about the best duo partner for a THF. Pretty much a THF/NIN is one of the best end-game soloers out there. So when you talk duo, you are talking about 2 people who can pretty much take on anything. If this is not a contest of who can kill the fastest, but instead who has the largest array of monsters they can duo, then THF turns out to be better then the ones you listed. If it is a contest of who can kill the H/NM faster, then probably MNK/NIN or WAR/NIN would win that game.
The patch introduced something new though. Certain HNMs that were soloable by THF no longer are b/c of the god mode they go under (see IDDQD). So if a THF were to duo these now, they would need a partner that can do considerable DD without getting killed. I guess in these couple cases a WAR/NIN would be better for duos. There is another option where a THF could duo them with a SMN. You get the best of both worlds. A THF tank that can keep hate and a healer that can DD without taking hate or dammage.
