Ok - so maybe you are getting "negative" comments because you made a poll out of something thats fact. Its like making a poll to see whats heavier - 10lbs or 20lbs or 30lbs - if your question was - which one is better and why - then thats a different story.
Honestly - shaving weight off your brakes isnt gonna do all that much unless you track your car like travisJB does - and even if you do - you probably want a nice hefty rotor which can handle a lot of abuse from a track pad in high heat - and historically - the lighter your rotor the thinner it is and the thinner it is - the more crappy it is on a track etc etc.
A lot of people seem to be weighing the caliper / pad / rotor combo and they see that they saved 2 lbs over stock and they rejoice that they are saving unsprung weight - this is not true - only your rotor turns in that assembly.
Not bashing your thread but just saying - if you gonna make it be about opinions then polls make sense - but when you can measure these rotors and see which ones weigh the most - makes no sense to make a poll
