I am the odd one out as far as projection and sillage. The extraits last forever for me but after the first couple of hours they do not project. 3 full sprays to the upper chest and one to the wrist and they are like that.
Grev, on the other hand projects like a beast with just one spray. This is how it usually works for me with EdP VS Extraits. The EdP's usually project more and leave a trail. It seems odd that Grev is the opposite for most here opposed to the newer Extraits!
