@Markus: Why this summer?
@Mr. Wookie: Yes, Lucas lies.... about his own "creation". And all the authors are right.
I think some of the troopers are clones. A few older ones and a lot newer ones. And some of them are recruited from the citizens.
To the topic: I think, you should read this in some Star Wars books and look all movies with Troopers.
And Wookies could sprint. In EP3, at the beginning of the Kashyyk Battle, they jump up and some of them sprint down the beach then. But not as fast as the Clones.
PS: Why they should give up cloning, and stop building a bigger army?
