Well, Dooku clearly manhandled Obi-Wan utterly and convincingly. It is also my belief that Katarn isn't as powerful as Dooku either. Put Obi-Wan and Katarn together, I agree the duo will most likely win, but Dooku did manage to knock Obi-Wan out in ROTS, if he could do it here, he could probably pull it off.
Kyle Katarn is very powerful and would work really well with an ally; especially a level-headed one like Obi-wan. Obi held his own against the Count BY HIMSELF in AOTC... granted it was for a short while. I think that this duo could affectively work as a team and eliminate Dooku, after a very tough battle.
It'd be close considering AOTC Obi held his own for a bit but was beaten as for ROTS Obi he got thrown pretty quickly so it's up in the air as for his value in this match.
Kyle on the other hand is quite strong and if him and Obi can stay together and keep the attack pressed on they should win but if Dooku goes one on one for any medium sized time he's got one of and then the other.
Whoa whoa whoa......during aotc obi wan got ****ed up and he wuld have been killed with anakin had yoda not been there. Rots he got seprated from the battle twice. Obi wan vs. Dooku is a massacre and kyle vs Dooku..............i dont even need to explain that. look i got respect for obiwan and kyle, there cool in my book. but lets be real it's Count Dooku, Jedi Master and Sith Lord
