Don't forget that Dragon Kick will only apply it's blunt resistance debuff if you are in opo-opo form, or in Perfect Balance. It's also important to note that while Perfect Balance is up, it completely prevents stances for the whole duration of it.. In the first rotation this would lead to 2GL dots without DK debuff, and in the second scenario to 3GL dots without DK debuff, the Dragon Kick at the end would not apply it's debuff (Perfect Balance would prevent Demolish from switching to opo form, while expiring after Touch of Death).
Been breaking my head as well over a good Perfect Balance rotation, for now settled with this:
Perfect Balance -> 3x Snap -> Dragon Kick -> Twin Snakes -> Perfect Balance expires, stances possible again -> Bootshine -> True Strike -> Blood for Blood + Internal Release -> Demolish -> Fracture -> Touch of Death
Focusing first on getting up GL to speed up GCDs, then apply fully buffed dots by the 10th GCD. Sometimes latency will prevent the first Twin Snakes from hitting, in that case I just replace True Strike with Twin Snakes later.
