There are certain regions that are under represented in agarwood oils, Laos being one of them. I've smelled only 3 other Laotian oils and if the DNA is based on those oils then Royal Lao is an entirely different entity. The others are great oils but do show evidence of extended pre-distill soak (injected artisan twist) that bends the profile towards barn Hindis IMO. Likewise, I've had the opportunity to smell only three specimens of heated agarwood from Laos and if the DNA is based on those woods then Royal Lao is a genetic match and represents what is intrinsic to the wood, untwisted. For your viewing pleasure, some sinking grade Laotian agarwood I scored from Feel Oud's Adam about a year ago. -------edit-------- P.S. while I do love Royal Lao and IMO it's obviously of higher quality, I prefer Keo from Agar Aura's Lao trio, it's more of this side of the Don Pearl.
