Hasty Touch II, Careful Synthesis III, Rapid Synthesis II completely replaced the previous versions so you can straight up replace them with the new one.
Manipulation II may also render Manipulation I useless. Manipulation II regains 40 durability with 96 CP. Manipulation I regains 30 durability with 88 CP.

I don't know how or when to use Patient Touch and Prudent Touch but I mostly use Focused Synthesis and Focused Touch which has 100% success rate if you use it after Observe, which means you don't need Steady Hand at all. The nice thing is Comfort Zone and Manipulation II work well with Observe + Focused combo. Waste Not and Steady Hand are wasted if you use this combo.

Initial Preparations is amazing if you have specialist. Use it on the first step, and any time later you can choose to restore 25 durability, 65 CP or add Inner Quiet Stack by 3 (great to use before Byregot's Blessing / Brow).
