Welcome to BaseNotes, Alain27.
1) Believe me, the sillage of Kouros is still there, even 6 hours after. It may be subdued to you, but others can still smell it, less than subtly.
2) It would be easier to recommend scents to you if one knows your own definition of "manlier". However, you could go to the Directory and do a search of male frags released say from 1970 upwards. That will take you though the power-scents era in which Kouros and Givenchy Gentleman belong. There is quite a lot of choice.
