Hmm, lets see...
I definately wouldn't take Agen or Saesee. Kit maybe. I'd take Plo Koon (this might piss some of you off). Yeah I like Koon but I hear from lots of places that he's really strong. I'd also for sure take Luminara Unduli. Her saber skills are supposed to be really good. For the third person I'd either take Cin Drallig, Quinlin Vos or Kit Fisto, I havn't decided yet. Cin's likely the best dueler out of the 3, not sure who's best with the Force or who has more experience. Quinlin probably has the most experience, I guess. I don't know. I guess probably Quinlin.
Well, I suppose you could pick Anakin, but it'd be like committing suicide.
I think the 3 I picked could probably pull it off. By the time Anakin came Sidious'd be dead, and if he wasn't Luminara and Quinlin could deal with Anakin while Mace and Plo finished Sidious off.
After seeing the movie, I'd rather have about 30 Jedi with me, in a more open space.

They should have sent Anakin after Grievous as Palpatine suggested... Then there would have been no Anakin to duel with. But then again, Sidious wouldn't have revealed himself if he didn't think it would be safe.
Heh, Agen was supposed to be a bizitch with a saber too, and he was the first to get pwned.
I'd take....Quinlan (at least he'd have the balls to use the darkside if things got hairy), Tholme (god knows why, he could probably tag team with Quinlan better than anyone else though) and Kit (he'd probably die, but that'd spare a few seconds to hit Palpatine).
Plo Koon, good choice, Mundi, not bad, Secura? What has she ever done to be given this honor? The honor of being above Kit, Cin, Luminara, Quinlin, Shaak Ti or even Agen Kolar?
If I were Mace I would smoke a big fat blunt and clear my mind with it, then I could take on Sidious all by my self through extreme concentration.
Oh wait.. Mace did beat sidious, so why do I even care?
Kit Fisto, supposed to be the second best duelist in the galaxy, good pick by mace, then I would simply wait for Yoda to get back... Wait i mean, i would be taking Plo Kloon and Ki Adi Mundi, Plo Kloon's supposed to be real good at this, and I'm not sure for Ki, I just like him.
