A lot of hazes and haze crosses have the incense aroma when burned. I love it also and when I catch a whiff, it immediately turns my head. If you want to join the search for the holy grail of Piff, a Haze derivative, check out this thread:
Piff has the incense, floral, musky smell/taste. I have yet to try any of the mentioned strains and breeders in that thread, but there’s a common agreement that these guys have been able to find very similar phenos to the original.
Old school Blue Dream used to have the incense smell when burned, but the Blueberry taste. I really miss that stuff. The bud labeled as Blue Dream now is typically not the same.
