MzM, I have very little experience with Indian Ouds and I haven't done much blending myself (though I do love to layer my ouds!). The Indian I used was the Nagaland from
riviera274, and it isn't a kick-in-your-face oil. And the Cambodi was one that I got from Feel Oud about four years ago (not one of his distillations, I don't think), called Purple Cambodi, which is a really fruity, plummy, earthy, deep oud.
If I was you and wanted to blend ouds, I would start off by layering on your arm, rather than mixing in a bottle. And, when you do move to a bottle, start small and use less of the more overpower oil in the beginning.
