Alright, so I installed this ROM and have had it running smoothly for 3 days now.
I have the E973 and I had recently been running just stock ota that I reverted back to a week ago.
So it does work on the latest OTA or kdz, I was already rooted and freegee'd.
Here are the steps I took to flash using twrp:
Factory reset
Wipe cache
Wipe Dialvik
Wipe System
Installed ROM
Flashed banks gapps 4.2.2 (found in chads cm 10.1 thread)
Reboot, then set all my settings in ROM
Rebooted to recovery
Flashed bell ICS modem from Houston (to fix annoying call ended bug)
Haven't had any issues so far 3 days strong.
Thanks Paulicat

Thanks a lot for the update, glad its working well for you!
I'm going to try to get in touch with Houstonn regarding the modem issue.
The jb modem I linked in the first post seems to work fine, but the jb modem from houstonns thread has the call ended bug.
I was certain the modem files from my first post were also from Houstonn so I don't know what the difference is just yet.
Im testing an updated rom with latest commits from CarbonDev and latest houcha kernel.
I'll upload and update the first post on Tuesday.
