The biggest tip to capturing a Force-using character is pretty simple: If you find them and pin them down somehow... do NOT send another Jedi after them! They'll get detected, have a jedi fight, and maybe someone gets hurt, but that's about all that happens. This goes for trying to grab Luke, the Emperor, or Vader. My recollection, which is a bit fuzzy, I haven't really played much in years... is that this applies even to minor character jedi. I don't recall if they have a special message for minor character jedi detection and subsequent fighting(my first thought is 'no, it just shows up as foiled'), but I seem to recall it seeming like the result came out the same. What you want to do in this case is send a number of your highest combat rating 'normals' in. You're going up against the Jedi's inflated combat rating, so it's almost certainly not going to work 1 on 1. One trick to soften them up as the Empire: run an assassination mission first. Partially successful assassination missions wound the target, which lowers their combat rating. I THINK you can run assassination on majors, which is slightly misleading as they can NOT die, merely get wounded. (Can't verify atm 'cause my current game, I got Luke and Leia without hardly trying and Han is being...elusive). I do think I recall running assassination on Luke in the past though, specifically to lower his combat rating and make him an easier capture(it also keeps him from doing much of anything while you're trying to grab him, which is nice). I can't verify the minor jedi parts either...'cause Vader is being stubborn and not finding any.
