All mention of Sifo Dyas needs to be removed in my opinion. The stupid detective plot involving him went absolutely nowhere.
New crawl saying that a clone army is being created on Kamino, and that the senate is bickering about whether it should be used is all that it'll take - as well as removing obi wan's and the other jedi's surprise at its creation. The secret creation thing (along with never being explained) is utterly stupid. Why would the Jedi happily use the army, knowing it was commisioned by neither a Jedi or the republic?
Also remove the whole "missing planet" thing, where obi wan goes to dexter, then the archives, THEN asks a bunch of KIDS before going to Kamino. It was STUPID. Just redub the droid analysis deleted scene so that they say that the ore used to create the dart is from the Kamino system - maybe something about this being the location of the republic's cloning facility, just to clarify to the audience.
"Probably hand-made by a warrior yadda yadda yadda.......however I am detecting minute trace elements of Kaminolium. That ore is unique to the Kamino system if you hadn't figured that out, sir" :P
Possibly move part of Yoda's line of "And see this army they have created for the republic" to earlier in the film if he ever instructs obi wan to go to Kamino ( I don't remember)
That way, Obi Wan goes to Kamino under the ruse of checking out the army, when he's really looking for Jango. (or in my dream edit, Boba - the kid doesn't exist). Also we never see "Boba" unmasked. It ruins the mystery.
But I've said all this before I think.
But yes. I approve of Dooku replacing Yaddle in the council chamber. Sifo Dyas, on the other hand, belongs on the cutting room floor.
