Only been on a few Shinryu runs and none of which I have been able to proc - so AoA is out for me at the moment.

I use RR/GH/VV most of the time.. VV is the one I switch out if needed.

Sometimes throw in Impregnable Tower if I need HP
Mounted Champion if I am solo'ing /WAR. 20/tick regen is nice.
Might use an MDT atma as well depending on the nm.

They are usually reasonably situational.. Even though I don't have AoA to test, I would pretty much full time switch VV for AoA as well.
