My Great Taurus takes the Black Hammer (as +2S for GW no longer works on mounted models) with the Armour of Gazrakh. In my games, I whip him up the flanks to knock out war machines and stuff like that. After a turn or two of munching on poorly defended cannon crew, he then starts on the flanks of ranked up units. I normally find that the Great Taurus ends up doing much of the work!
And just so that my troops get that LD10 bonus, a CD Hero acts as my general.
