And usually of the 3 you have available, you can find a mixture of 2 that grant more progress, and 1 that grants more durability, you can rotate through all 3 and keep the durability up as well as speed up the progress. You will also note that as items become more trivial to you you will not have to work very hard to keep the durability up, since you will not lose much in the crafting process. When making basic oils, washes, and resins I have pretty much stopped using the Durability one and use all 3 to speed the process along, and get pristine every time.
