Angel by Thierry Mugler has tremendous sillage but it may not be suitable for very hot climes, as it
is quite cloying if over-applied.
I find Santa Maria Novella's Melograno will cut through most atmospheres
and it lasts quite well. Also Dior's Hypnotic Poison lasts well and is big on sillage.
The Estee Lauder's are reknowned for longevity and sillkage too. Why not try some of those.
