I'm new to BPAL, and this is the scent that taught me how much chemistry makes the difference. When I opened the vial, it smelled soapy - this was reinforced by my little sister, who compared it to the kind of soap you'd find in a public bathroom. We both tried it, and disliked it very much - it had an odd chemical tang.
I was talking to a friend about BPAL, and showing her the imps I had purchased, and she made an "Oooh!" noise, tried on Neo-Tokyo, and fell in love. On her, it smells fresh, and clean, and bright! So I gave her the imp - it was obviously destiny!
