I'm not sure about Visas Marr's force powers, so I would say Jaina if the All out came down to a mostly saber battle.
In force, I'll let someone else decide. or persuade me who would be the better canidate to win this...
I kno Jaina can use Force lightning and supposedly has a crazy lightsaber offense.. as of LOTF anyways
some1 please state the extent of Visas' powers besides force sight. (she is the blind one right?)
I might be biased, but I'd call this a Jaina stomp. Not only does she have Skywalker blood, she knows shatterpoint and fought on a level near that of Darth Caedus. I know there were mitigating factors in both fights, but she almost kept up with him. During their first fight she almost got the better of him. This isn't really an impressive feat (he thought she was luke and had one arm during their respective fights) but when added to her other attributes (godly [godessly?] piloting skills, unorthodox fighting style) she comes out on top.
We don't really know much about Visas anyway, so the point is moot.
The presence of an unknown and my bias for Jaina means this will go to Solo.
