Here's my rotation for 80 durability on specialist classes. I usually run these 15 steps as a starter macro.
Initial Preparations (preserves CP, gives finishing options)
Comfort Zone (80 CP for cost of 66)
Whistle While You Work
Inner Quiet
Careful Synthesis II (buffer for M2 durability restoration)
Manipulation II (steps cost 10 durability, then restore 5)
Steady Hand II (50% less fails than Steady Hand)
Patient Touch (chance for 2 stacks of Inner Quiet worth it..
Patient Touch (.. when you have no stack to lose)
Hasty Touch II (HT2 with SH2 is 90% successful)
Hasty Touch II
Hasty Touch II
Comfort Zone (CZ wears off, so we refresh)
Careful Synthesis II (buffer)
Manipulation II (M2 wears off, so we refresh)
After this macro, I usually press Steady Hand II and wing the rest.
