First of all i would like to say that Ms. Carano has proved to be very brave accepting to face Ciborg. Other famous fighters weren't so brave. I'm thinking in Layla Ali who has avoided fighting against Wolfe or Ragozina or in general every boxer who really could hurt her. It is very important to remember this.
I'm not sure i'd like to see Ms Carano fighting Cyborg again. Ms. Carano is a great athlete and a good fighter, no doubt about it, but in my opinion Ms Santos is stronger, faster and has more killer instinct. Sadly, i think that only if she is out of shape would Ms. Carano have a chance to beat her. With Cris Santos looking just like Terminator

it would be very very dificult for any FEMALE fighter to beat her.
Gina Carano is beautifull, brave, intelligent, famous, she has earned a lot of money and she has proved that she really can fight. So now she has a lot of things she could do in many different areas. She has no need to be hurted fighting with beast-fighters like Cyborg Santos.
