I'd like to hear more about this Assam Kinam, I see it is from Meghalaya, does it share any commonalities with Oud Nuh or Oud Isa? How is it?
I have only tried Assam Kinam and Oud Nuh a couple of times, as I only have sample vials of them given to me by very generous friends. Because of my lack of experience with the oils and minimal encounters with them, I'm afraid I'm not the best suited person to answer this question.
What I can say is, where Oud Nuh has more fruity undertones behind the indolic Hindi aroma, Assam Kinam boasts a strong smooth indolic Hindi base, but as it proceeds to the drydown, the oil shows hints of a light mineral undertone (almost similar to a mineral note apparent in Sultan Murad, albeit very very light).
Take this with a grain of salt (maybe a pound), as I'll need more wears with both oils and this comparison is just from my memory.
I haven't had the opportunity to try Oud Isa though, nsha'Allah in the future.
