Cin,s one, Dooku's another, Quinlin Vos is another. I'm not saying the Council Members are the 12 strongest Jedi, merely stating they are powerful. Most of them, anyway, the exceptions being Coleman trebor and Saesee Tiin.
Janus, I never said that she didn't have a prayer. I'd give her the chance of victory against Obi-Wan. In, as you said, what would be the longest duel in history. However, I simply view him as the superior combatant. Obviously not by any considerable margin however, as I made clear in past posts. If I say she could defeat Asajj Ventress, then I hold her in very high regard. Again, she is likely in the top ten duelists of her time, after 'Le Six', and maybe Cin Drallig.
And, yes, that was Ti. Although that was an idiotic occurrence to say the least. Not impossible, but it would hurl her up in the ranks to a level that shouldn't be hers.
