Once you hit around level 56, your 40 durability crafts turn into 35, which are a royal pain. Crafting them is still doable, it just becomes too complicated for 15 lines.

Here's what I'm using for crafts that require 3x Careful Synthesis II to complete. The base here is 339 CP, if you have more you can upgrade Hasty Touch to Basic Touch. If you have a lot more, you can check out this variant that lets you accomplish it in two CS IIs.

Part 1:

/ac "Hasty Touch" <me> <wait.3>
/ac "Hasty Touch" <me> <wait.3>

Part 2: (Swap the first synth for a touch if you can craft in 2x CS II.)
