I really do think I have a more discerning nose than other people, which is good but frankly a lot of scent blends are bad, overpowering, or artificial to me. Does make finding good soap scents a bit easier, though.
I've made soap and lived with scent-sensitive humans, and I agree with you on how bad so many soaps smell.
From my own soap-making experiences, I stick with essential oils only, and don't do more than 3-4 components in a blend.
