Which scroll to get?

Ok I have a clean Fafnir 2h sword I been waiting to scroll in case we get the 50% Red 8w.att scrolls. On my main I can get 4 Shield/Safety scrolls and 2 Protection scrolls. I have 5 mules where I can get either 1 Shield or Protection scroll. My question is which scroll would be best for me to get. One that saves slots when scrolling or a protection for enhancing the sword when I finish scrolling. Personally I am thinking of getting the Protection scrolls for getting the enhancements on it. Just wondering how others may feel.
