Incense Extreme is nice, but itself won't bloom in heat. I'd prefer it on a cool, gloomy, windy autumn/winter days, esp. before a rain with dark clouds dominates the sun. IE evokes a dark, mysterious feeling to me, like you enter an old Asia temple.
I tried it on a summer/hot day once, while the incense is still something I admire, it became rather soulless/boring.
On the other hand, IR does well in the heat. No complaint, sillage is big. Even 1 spray can get you compliments from people standing few steps away.
