If you want C-99 and a very nice yield I would go with the agent orange, you can get a C-99 pheno thats just as potent with a better yield. It also has an amazing orange creamsicle flavor and turns pinkish maroon in the last weeks of flowering! Subcool has the best gentics out right now imo, check out his sub forum in the organics section. He has very detailed long descritions of each phenotype of each strain so you know which one to choose, I dont know why all growers arent doing this but they should be!
