I own Bois des Iles EDT & Parfum but given your comments I wouldn't suggest you blind buy it.
Two reasons: (a) the aldehydic opening will probably have you running for the hills, and (b) the sweetness, what some call 'the ginger bread note' might be too much for you.
My suggestion (given Egoiste / sandalwood / classic styling seem to be your broad starting point) would be to try Tiffany for Men, which was composed by Jacques Polge, who created Chanel Pour Monsieur Concentree (and in the same year) and so far seems to have dodged the IFRA reformulation bullets flying around, and also, just for the hell of it, the new Dries van Noten Par Frederic Malle, which I predict will become a cult classic when more people get to know it. It is not the same scent as Egoiste but it has the same sense of satisfaction for me and looks like being the first of a new breed of sandalwood scents using some actual Santalum Album (Olivia Giacobetti's L'Arbre from IUNX) being the second.
You can buy either of these blind and if you don't like 'em tell everyone it was my fault
