I have been told these scents are similar. My reference point is Envy, which I have smelled many times. I enjoy the smoothness in Envy, but the woodsy note slightly puts me off. Also, it is a frag worn ALWAYS by a good friend of mine (no matter how many times I tell him to check out basenotes!) and I'd rather not smell the same as him if I can so help it.
Anyways, I am very curious about Floris Santal and Jaipur. Perhaps you could compare and contrast them for me?
