IMO, the Satori is a better up high and I like the flavor of the Satori better. But C99 is a great strain and she takes a little less time than Satori. I usually took my cindy out 7-8 weeks and take the Satori out 9 weeks.
I grew Joey Weed's C99 also. I did do a run of Mosca's C99 which was good, but they weren't fem seeds. I don't really care for fem seeds personally and if I have a choice, I buy the non-fem.
