I'm not an analytical person by nature. I spray, smell and then decide if I like the collective whole of the scent.
After I decide, whether I like it or not, I will make an attempt to pick out what's favorable or unfavorable. Too much thinking and not enough smelling / enjoying would not work for me....however, that is the way I decide on a scent.
I used to be a songwriter and every song needs an intro, verse,chorus/hook and an outro. One part of the song usually is more excellent than the connecting parts, but it's the collective whole that matters.
Frags, like songs, either move you or they don't. Once you start dissecting your favorite song in order to understand what it was exactly that was moving you in the first place, I guarantee it will no longer be your favorite after all that analysis.
