I ended up making my vanya robe today. Had 348 craft, 348 control and 330 CP (372 w/ HQ bouillabaise).
The 2 star 40 durability item (vanya silk) was really tough. I followed the rotation but screwed up and had 10 durability left with slightly less than half progress, 90% HQ chance, and very little CP left. I took a gamble and used steady hands + rapid synthesis and thankfully it didn't fail and got me to finish.
The vanya silk robe material and subsequent robe of healing were much easier and were basically 100% HQ with this rotation.
