If you have your hands on anything with hogsbreath or p91 you've made an excellent choice! I grew p91 for almost 7 years and it was an unbelievable strain. Over the years though, it lost it's vigor. This could be largely my fault as I did not take the care as to single out only one (best) mother plant/source for the entire duration. I took clones off of every plant for the most part, and only planted (what appeared) to be the best ones at the time. A lesson to be learned is that many times the plant the veges well is not always the plant that yields/smokes or has the best bag appeal. Hogsbreath was something local to Carlsbad where I lived and knew a grower of it who would NOT part with any clones. (bastard!) While I felt the P91 was every bit as good as the Hog, you always want what you don't have. Let us know how your experience with that strain goes and please post a journal.
