I'm pretty torn between these three Legendaries. DHC is the one that extends SEF based on chi consumption, Katsuo's reduces FoF cost by 1, and the ring gives me the chi orbit talent for free. If anyone has any insight, I'd be all ears!

DHC and Katsuos are probably the best choice for this content. You can also try ring for heavy aoe fights like mistress or harj.
