I used all NQ mats for mine, and hit about 90% HQ rate overall. When you factor in the time to make 1-2 HQ 40 durability 1 star items, plus 1-2 HQ low level 40 durability items, you're spending about the same amount of time.
You're looking at 2½-3 hours per craft, which is right at the same average speed I was making NQ products plus the final products.
