quite frankly, i think the top pic from ESB is perfect. That's how lightsabers should look. flickering & humming with powerful energy. I think the newer sabers (such as the prequels) look too perfect & cookie cutter. they dont look as real. I would like to see all sabers look like they do in the closeups from OOT ESB (where the blades look fairly skinny). There shouldn't be a perfcetly defined white core surrounded by a perfectly defined colored corona. It doesn't look natural. Oh, & the tip should not come to such a defined point as it did in ROTS. Remember, this is flowing energy.
