Custom ROMs for Galaxy Nexus (Sprint)

I'm getting a new phone (Sprint Galaxy Nexus) soon, and as a custom ROM fan, I was wondering if any of the Verge readers had suggestions for custom ROMS.

I've got CyanogenMod 7.2 on my current phone (EVO 4G) and have been pleased with its performance. But I'm curious what other ROMs I should consider trying.

If you've got a Sprint Galaxy Nexus, what ROM are you using? What's performance like? Battery life? I'd love to hear your recommendations and thoughts. Thanks!
