Hey, RedFive! In my opinion, Spence's edit of Attack of the Clones is the best so far, compared to Attack of the Phantom's lower AV quality and lack of a proper crawl. Although, if Attack of the Phantom was updated with a proper crawl, better AV quality, and without the Yoda fight, I may reconsider. As for Revenge of the Sith, I think hands down that Kerr's Dark Force Rising is the best ROTS edit yet! I personally like it a lot better than Stankpac's edit, which didn't seem to cut as much.
As for the future, I think that Trooperman's edit or Brash Stryker's edit will be very awesome edits of AOTC. I haven't seen the workprint yet, but would like to. Can anyone help? Also, Bob Garcia's edit of ROTS is definitely going to be interesting!
