From the parses I've done the DE > SF > MU > AE gives me the best results on single target fights for burst openers. SF and MU are the highest potency moves we have and capturing them under TA along with aeolian gives a nice boost to dps (and also almost always pisses off the boss and steal aggro. Lol) In the long run it will even out either way so long as you don't let the timers fall off.

I think armor crush fits nicely in the rotation. It is by far my favorite ninja move at this point because it let's me cast damage mudras endlessly.
