A saber hilt is not heavy!! I'd would rate it at - let's say - Apple-type weight!!
Pick up a banana, hold it like a lightsaber hilt and wave it. How complicated was that? Even monkey's can manage it...
Bah - I'm giving up. Kray may disagree with me about saber throw, but at least he got the point I was trying to make...!
*ceases to bang his head against a brick wall*
Ahh! That's better...!
