I avoid Traya teams - they smush me. So I generally try to fight mirror matches against other Bastila teams until I have no choice. Against other Bastilas, Old Ben is pretty useless, as he can't land his Mind Tricks against that kind of Tenacity. At least GK hits decently with the buffs and can call a massive assist. Against Palpatine, I can see choosing OB because he can probably delay special moves for a round or two with Mind Tricks.
I generally run the commonplace zBastila (L), zzGMY, zHoda, zEzra, GK. But when I fight other Bastilas I'll replace zEzra with zVentress or zThrawn. Works 90% of the time. =)
