Hi mokelembembe. I admire your collection! You already have many good bottles. I think a man could be happy with just those! But if you're asking what else might be good to add, maybe some newer fragrances, made between 1995 to 2004. Maybe one or two fragrances with citrus, even though you have a long winter. One citrus I recommend is Eau de Rochas Homme...citrus with vetiver and light wood.
Maybe Geir, which I think is floral with herbs and light wood.
Since you like some classics, you might like Halston Z-14--dark, with herbs, citrus, florals and leather. Reminds me a bit of cranberries!
Perhaps Lanvin L'Homme, kind of like wood, citrus and pepper.
Do you know what you'd like more of--citrus, floral, wood, leafy green, spice, leather--any of those?
