My thoughts on the subject of technology.

CLOAKING DEVICE:
I think the enemy having a cloaking device, and the threat of enemy ships just appearing and attacking, can be very dramatic, exciting, and Star Warsy.

I think the idea of a plot revolving around aqcuiring cloaking device technology starts to feel a little to 'sci-fi' and not as Star Warsy.

CLONING
Somebody refrenced the clones as 'dopplegangers' and that resonated with me. Replacing people with evil clones has a kind of mythic quality. (Although I still prefer cloned shocktroopers, which totally eliminated much of the scifi/cerebral aspects of the cloning question).

I don't care for the idea of cloning specific Jedi, insane or not, to recreate force powers. It makes Jedi too biological and makes the cloning too scientific a concept.

MITICLORIANS
Interestingly, I've never minded midichlorians. For one thing, we already knew the Force could be inherited ("The Force is strong in my family") and for another, it served the story purpose (which I think is the reason the entire concept was created) of identifying lil' Anikin as megapowerful, possibly the chosen one. But making miticloriens the basis for cloning evil Jedi with force powers I think crosses the line away from the Mythical Space Opera elements of Star Wars into something else.
