I've tried three JB ROMs so far and this is hands down the best I've had yet. My phone has never been this snappy.
DroidTh3ory has introduced a new install script named CMPLX6 that handles ALL procedures of the install for you. Each build will install the way that is needed for the update at that time. No need to wipe data/cache/dalvik...it does it all. Just install and flash.
There is also a modded launcher in the OP of the thread that takes the Google Search bar away, 5x4 grid and makes the launcher faster. You do need to wipe cache and dalvik to flash this mod but only do so AFTER the ROM is installed or you'll loop.
Here is the link: | ROM | AXI0M ENGAGE | JELLYBEAN | 4.1 | MAGURO/TORO - GALAXY NEXUS -TORO - droidHIVE Forums The mirror is active if the original isn't.
Feel free to join The Hive and check out what DroidTh3ory has to offer. I know when the GNex first came out, he was big time over here and very well respected.
I just proof read this and realized I sound like a complete Axi0m fanboy but I can assure you I'm not...yet. I'm a Gummy junkie through and through but when I found this when exploring the JB ROMs, I just had to get the word out. Give it a shot...I have a feeling you'll enjoy it.
Again...this is the best JB ROM I've tried BUT as we know, every phone is different. With that being said...if you wanna give it a shot, MAKE A BACKUP in case your experience isn't as glowing as mine.
