Gave a golf buddy a CAO Rabid Reindeer that he said gave him a buzz and really screwed up his golf game. He only smokes on the course when I give him one and he's had LFD's and other full sticks before but that was the one that he had to put down (usually burns his lips) and said he didn't mind not having another.
I haven't tried it yet myself - bombed out the ones I grabbed and just bought some more, but @DogRockets loves these things so maybe he can weigh in on it.
I've heard some of the Obsidian and the Cu Avana Punisher are really strong smokes.
