You dont have to worry about that. Unless your not trying to pollinate the whole plant, male plants will burst their own pollen sacs and spread the pollen them selves so you dont have to worry about that. But if your just trying to pollinate a few buds you dont have to worry about getting a male with the best characteristics. If you bought some seeds that you like in the first place and the male has made it to it's pollen spreading stage and is healthy then there is nothing more to desire for a healthy male plant.
