Good luck with that!
All ICS and greater ROMs have issues on the OB. I got tired of all the SD card unmounts, loss of touchscreen, and other crap issues and went back to Marvel 9 (GB 2.3.4, with the "There is no delay" patch).
The ROM I've had the LEAST issues with was Marvel 12 (ICS); the only significant issue I ran into was a loss of all touch/swipe input. It would usually happen during an incoming call. I would miss the call, of course, and have to remove the battery to reboot the phone.
