i ran chocolate rain, good yielder of some lovely, stunky buds.. no chocolate smells or taste in the ones i ran, more skunky / hashy imo..
I have grown out about 10 so far and seeded one up really well so I have hundreds of seeds to go through, but out of those 10 or so, I havent gotten any I would call "chocolate" either. But I do like the buzz. While not the most potent of strains, it is certainly the right buzz type for many activities.
