My opener is as follows (with potion)

Heavy thrust > BL + BotD > Impulse drive > Dragon sight* + B4B > Disembowel > Potion > Chaos Thrust > GSK > Wheeling > Jump > Fang > Mirage > True > Spine shatter > Vorpal > Life surge + diversion** > Full > DfD > Fang > Mirage > Wheeling.

*Dragon sight can be double weaved if the person you wanna target is 2nd in the party list, which they should be, on controller. It will fall off after the 2nd wheeling thrust at the end of the rotation and depending on skill speed should be back up just after full thrust later in the rotation.

** For lakshimi since I don't typically trust healers in solo tank parties to keep the prey alive

Without potion you can move GSK and everything afterwards forwards but delay the GSK a little bit so it gets the buff from the disembowel, it probably won't work though due to the length of the animation.
