I am by no means an expert, I am very new at this myself. But, my understanding is that pour temp doesnt affect scent throw, only how the product sets up. I believe just the temp at which you add fo affects how the oil binds/blends w/ the base product, and there are varying opinions about which is better, higher or lower temps. I add my fo around 160-170 now, I used to add at a little lower temp, but I got impatient and more of the literature out there seems to say better to add at higher temp, so thats what i do. Hth,
