Bane vs. Mace in a force fight? IMO, Bane wins that.
Didn't you say:
If Sidious could match Windu and then overpower Yoda with the force with no practice for ten years, Bane doesn't stand a chance.
Either of those force-fights, would be, in my opinion a toss-up. Yoda would need a lightsaber to beat Bane. So saying: Sidious can match Mace in the force and overpower Yoda with the force (which didn't happen btw..) means that he definitly beats Bane is wrong.
You just haven't substantiated furiously though. It doesn't say that Mace is invisible in ROTS. Invisible in shatterpoint, to Kar Vastor, but perhaps not here.
Saesee Tinn, and Agen Kolar being the order's greatest Swordsman (and the quote says some of the greatest swordsmen, btw... means little when it comes to using the force. Nowhere is ANY indication given that they are gifted with strong force abilities. Anoon Bondara was the most skilled swordsman as well, but he wasn't that good.
All that aside: It boils down to this: And if you are going to address something, address this: your paragraph answers which prompt MY paragraph answers are annoying to both of us, i'm sure.
1. In my opinion, Sidious DID speed rush Agen Kolar and Saesee Tinn. It is the simplest explanation. I think he was just better than Fisto.
2. None of those three are ANYWHERE near Bane when it comes to force ability.
3.Maul/Yoda/Mace have all 3 successfully crossed blades with Sidious without being overwhelmed by his speed. Bane has comparable force ability.
4. The quote "furious" speed is nice, and if you are going to say that he was using "invisible" speed in his fight with Mace, great, but considering Maul was able to keep up with "invisible" speed, and Padawan Kenobi was able to keep up with Maul....
I think you are really underestimating Bane to say that Sidious can simply speed rush him. Sidious didn't do that to any of the top-tier combatants he faced, and Bane is DEFINITLY top-tier by all indications.
Your lightning idea is better, but he must successfully disarm Bane first. Not saying it couldn't happen, but it would be difficult since Bane doesn't have to pay any attention to protecting most of his body when fighting.
I'm still of the opinion that this fight is a toss-up. I picked the fight because it was the closest fight I could think of for Bane.
