Best Rom/Kernel for Battery Life

[bonanzabucks]

I'm unrooted, but probably going to root my phone in the coming days. What is the best ROM or Kernel for Battery life? I don't really care about the themes as I can customize my own phone; just care about my battery life. Thanks!

try freegs3x".. based off of cm9, but lot of customization

I find the roms based off of stock (tw) seen to be the quickest as well as having the best battery life.

As for kernels, again it seems like the ones based on stock show the best combination of speed, stability and battery life. The Sprint gs3 seems to have very few kernel devs.
