I definitely use whites on all my chars, weighs way less than all the healing items except cake. I only know a few people who use rank whites on PvM purposes. But this is niff wise sometimes I'll use meat when I need of healing without wasting money. But Mjor+niff+whites=profit if you get the handle on conserving,preseving,and then consuming ;3. Plus you don't have to work as hard when you do it this way and can constantly niff without just spamming meat in niff and only have to spam the white 1-3 times on a big mob if you get the hammerfall in right.
