The men don't really need to be obviously stronger than the women for the story to be told. In fact, aside from a handful of outliers I don't think RJ gave it much thought because he also considered dexterity as an equalizer. Not really a concept that would play all that well in a TV Show IMO. Might be really interesting to see something like that executed well. We'd really ONLY see effective Strength and many people may have a different view of the OP and "strength". Even make us see it in the way the AoL AS saw it.
