Yoda Luke Obi and Mace against Sidious Anakin Vader and Dooku?
Now the two weakest here are obviously Luke and Vader..
Still Vader owns Luke, just look at ESB if he really would have wanted to Luke would have died in ROTJ no denying it. Luke was nothing special then, so Vader wins.
Obi against Dooku, we have already seen Dooku win this in ROTS... He will do it again and Obi will end up dead as pie.
Mace against Anakin? Now this will be a nice fight, but Mace will win this one, Anakin does not have the control to defeat somebody like Mace (who btw, would have killed Palp no matter what you say 2005, he was in control in the entire fight and he could have finished Palp off in a second if Anakin would not have walked in.)
Yoda against Palps, Yoda takes this one... We have all seen it in Rots, unless Palps can run away and has troopers coming quickly he will lose. Yoda was more then a match for him.
So that leaves Dooku and Vader against Mace and Yoda, who both had pretty tough fights. But the Jedi will still win this one. Mace is more then a match for Vader and Yoda more then one for Dooku. Both the Sith Lords will end up dead soon enough.
Jedi take this
