I must add Hiris to your list. Certainly springtime and summer that isn't densest heat summer, Hiris is dark iris in cold shadows. Just fantastic juice and completely different from Terre and the Jardins.
Of course one could wear it in steam bath heat, just like you could wear anything there if you were to make it a signature scent, but my instinct is that it will be better in all times when the nights are still cool. If the weather makes you sweat in your bed, I'd not use Hiris, but I haven't tried it either. I think the stuff is cool, sly, spring/summer triumph. Also, in my springs, the flowers are blooming in the boulevard medians I walk past, and the bushes around the old apartment buildings that are now condos. So springtime smells naturally of light flowers. Hiris takes this and makes you king of the season.
Equipage is pretty good for these seasons too, and I think one could be pretty cool trying out Bel Ami three times through a summer.
