I don't think anyone has actually weighed all the sabers since the weight can vary due to personalization (emitters, pommels, blade size, electronics) There is a thread on sizes that might help you guess at weight. I'm sure someone who owns one of these sabers can chime in on how the weight of those sabers feels.
Here is the link for the thread on sizes
