I bought my VM S3 Friday. I rooted and have made a CWM back-up, before i re-installed Titanium Back-up and after I installed all my necessary apps, then made another back-up. I am thrilled with the phone thus far. No issues. Here's my question: Knowing I can revert to the back ups, is there any reason not to try this ROM? I have used the Harmonia ROM's on my last two phones, simply because of the simplistic, stock build. I want to do my personal tweaks, but at this point, do not want to sacrifice any performances. Any input would be gratefully appreciated.
