Just a note on this opener, because you are coming out of PB, the second use of DK will not re-apply the debuff, meaning it's going to fall off around the time you are using boot/true in the next cycle. In order to keep up the DK debuff the opener should be:
With PB: Demo -> BfB -> Snap -> IR -> Snap -> Howl -> DK -> Steel -> Snap (PB is off, no stance) -> DK -> Twin -> ToD -> Demo -> DK -> Twin -> Snap...
This causes an overlap of back to back Twins in rotations resulting in a slight dps loss (50 potency) but I believe that slight loss is taken because most monks prefer using DK>Twin and Boot>True for less required moving.
If desired this could be altered by replacing the second Twin with a True, and continuing the rotation from there on with Boot > Twin > Snap...
