Probably small amounts. Incense Oud is rather rose-centric, imo. Pure Oud I haven't had and Oud Wood just once. The longevity of high quality pure oud oil is incredible (like I said). If you like the fragrances you mentioned, definitely get a sample from AgarAura. It will set you back 20-35$ for 0.15-0.2ml (incl. shipping worldwide!), but you'll have quite a few applications because literally a dab is enough (and I don't mean what's meant to be a "dab" w/r/t parfum/éxtrait, which I need four, five or eight "dabs" of). XerJoff Zatar captures the essence of oud the best so far, imo. There's real oud oil in there. Begins very fecal. Turns wonderful. But I guess for those 600$/100ml you could get 2.5-7.5g pure oud oil of similar or higher quality and get much more wearings out of it. Because Zafar literally smells like plain oud. Also, it's just one region -- just read a little on agaraura. There's quite a few regions that produce oud oil and all of them are distinct from each other. http://agaraura.com/ouducation.html This reminds me, I need to try to layer Incense Oud with some oud oil.
