If GL has said that stormies are clones, how can this issue even be up for debate? So not every Stormtrooper in the OT has the same voice or is the same height ... so what? Those who don't believe Lucas need to remember that these are fictional films. Casting, budget, time, and technical ability (real-world issues) made it difficult for GL to make sure every Stormtrooper in the OT was the same height. But, the intent/implication was there (the armor, never seeing their faces, "Aren't you a little short for a stormtrooper), and that's all that matters. Don't take it quite so literally, and go with the flow of what GL is suggesting in his movies.
