I agree with kimval. I do not enjoy seeing our fine women fight to the death. It certainly is not my fantasy; I don't even want to see the women badly injured. A black eye, busted lip or a bruised boob is quite natural in a catfight but the victrix should be satisfied in dominating and humiliating her adversary without causing serious injury. I would much rather see them take their lumps and come back and fight another day whether it be against the same woman or a different opponent.
That said, I will that Kylie would dominate this fight despite her smaller size. Her relative youth and conditioning would overcome the aging, but loveable LaToya.
Now that she is older, La Toya does not have the 'fire' to fight another woman. She is by nature, like her brother, a very gentle person. She would rather make love than make war. With the bed as their battleground; however, Kylie might find much more difficulty (and pleasure) if she locks up with this hot sepia beauty.
