What are you looking for in a frag exactly? Any specific type of scent or note? What fragrances do you currently have?
If you're going to get anything from Creed, you can never go wrong with a bottle of Green Irish Tweed. I would put money on the fact that it would become your go-to scent in almost all situations. Original Santal turns kind of feminine on me about an hour in, and I'm not a huge fan of Black Aoud. Tell us more about what you're really looking for. Have you sampled either of these two?
