DE > SF > MU > AE gives me the best results

Yea, DE is pretty aggresive opener, this falls into personal opinion so I won't tell you your option is bad. NIN is cool because of things like this.
Of all the combos MU is the weakest instant damage, which gives the Tank the most time to build aggro without us stealing the spotlight, which I guess has been the case more often than not with unprepared tanks for you, Shadewalker ftw.

After all we are comparing a 60 potency GCD against a 150 potency GCD.
Please take into account that DoT's worth comes with time.
In a 30 seconds parse, an opener started with MU > SF > DE will do more damage in the short term than DE > SF > MU, because the DoTs will have more active time.
Besides, DoTs damage isn't affected by DE's slashing debuff, so there is no point in placing DE before MU and SF for their DoT property.
DoTs then are better on the sooner they are casted on the oponent.

The reason of why I prefer mine is just for my habit of opening the boss battle with 0 seconds Huton wait time. Since it works for me as a filler for 20 seconds for the real thing.
