Custom Kernel Recommendations?

[HNNNNNGHHH]

Anyway, so I'm currently using CyanogenMod 10 Stable on my T-Mobile Samsung Galaxy SII (T-989). Everything about the ROM is great.....except for the battery life. Now, this doesn't bother me much at all since I always bring two spare batteries and my phone charger, but does anyone have any custom kernels that work on CM10 with excellent battery life and stable overclock capability?
