You could leave well enough alone if your happy and stable... or...
Honestly if I was to point someone new to ROMs, etc. to a good stable ROM, I would direct them straight to the new Bonsai 4.1.1. I ran the beta version for about 2 weeks and had 1 FC of my own doing otherwise solid as a rock and that was Beta mind you. Now its in full release and I've been on it for 2 days or so and it continues to carry the same tradition as the beta.
1. Its snappy, and speedy... Due to having its own custom kernel which I leave at complete stock settings.
2. Most bloat is removed to downsize it.
3. Has a battery mod and Zeam launcher and the clock removal in the status bar (if you touch the status bar it shows you the date/time so don't worry..) Otherwise its stock themed, do as you please from there.
I think its worth a look if your interested, I think you would be very happy. I would Odin to EC05 then use the
Bonsai MasterKey ROOT and CWM/Recovery Tool to root/install CWM on your device (its literally a 1 click operation and a few minutes later your done). Then flash the Bonsai ROM already sitting on your sdcard when your done, naturally follow the Bonsai installation instructions and you will be fine.
