You want a strong virile male, to keep the line strong, not a pansy.
What caused the male to hermi? A female may hermi because it wants to make seed and has not been fertilized. A male has no idea if his pollen fell on a viable pistil, (unless he can communicate with the girls, which some research suggests they do) so he did not hermi to ensure the survival of the species like a female might.
Again I would ask �Why has cannabis evolved into a Dioecious species?�`
Cut and pasted from Wiki;
Angiosperms
It is thought that flowering plants evolved from a common hermaphrodite ancestor, and that dioecy evolved from hermaphroditism. Hermaphroditism is very common in flowering plants; over 85% are hermaphroditic, whereas only about 6-7% are dioecious and 5-6% are monoecious.

It takes a lot of work (evolutionary speaking) to become a Dioecious plant. There must be an advantage to the cannabis species to have invested all that work. So nature (cannabis species) is trying to make it�s self Dioecious and the breeder using hermi plants is trying to do the opposite.
Is the Male Hermi a throw back to when the speices was Monoecious? If so then the breeding program is headed in the wrong direction. I should also note here another rule of breeding. Genes get passed down to offspring without change, unless mutation or some other factor is playing a role. So every cannabis plant is capable of being hermi. It has been that was (basically) forever.
What caused the plant to hermi is a key to the make up of the plant. The more stress needed to hermi the more evolved the plant is, not to say it will not revert back very quickly over several generations of abuse to a hermi strain. Selection is key when breeding and whenever I see a hermi (under good to great conditions) I kill it. Some people have grown my seeds, we all grew the same seed lot, and one person had hermis, others or I did not, (but with the right stress they will hermi even when using a strong virile male and a stress tested female.) So if the person who had the plants hermi used the plants for breeding then the stressors have already turned on the survival switch and for the next several generations the seeds will be prone to hermi under very little stress. (so if that was the male you are using ... gulp) Where as the other people may not have as nice a plant, but achieve better results because that stressor never pulled the trigger on the survival switch. The switch is still there though�.

: While it's true the single set of flowers at the node develop into full flowers I refer to them as the pre-flowers long after development just based on the spot and to avoid confusion.
