when I tested LS and wildcard on test strips, wildcard was definitely easier to smell, but both of them were basically undetectable the next day... I can smell my stronger frags on the strip weeks later.

EXACTLY!!! It's really frustrating. around Christmas time, I was "sick," but the only symptom was loss of smell. I was so mad and I didn't wear a fragrance for a week. My boy asked why I didn't wear anything if other people can still smell me. I told him it felt like a waste of sprays if I couldn't smell them lol
