I've ordered fem versions(100's) of every cup winner from every year from every country I found and never had a hermaphrodite result, except one, likely in the top three all time best cultivars, Tahoe OG Kush. I corrected the sexual confusion with a product called Reverse, one time treatment ,and have cloned her countless times over almost a decade.
concentrate on your atmosphere controls-, temperatures day and night, RH, water quality, organic habits, hid lighting, co2 augmentation- and hermaphrodites will be the last of your worries.
look no further than hso chem, tresdawg chems, chem91, strains. there is no better imo, its exactly what you seek I promise
