You're welcome. I am glad that the OmniRom build is getting use. I am a fan of their work and philosophy.
I actually got Omni on my vibrantmtd (sgh-t959) also and I love it. I agree Omni's work and philosophy is great and the fact its stable and fluid as hell makes it my go to ROM, including SlimKat. Love the fact it doesn't have theme manager that thing causes way too many issues as well as lag. Its cause of Omni I no longer use anything cm based. Users are sleeping on this ROM, thought it be getting more love from the community...
Are you experiencing low ear piece speaker volume when on a phone call? There is a bug on CM IIRC and my wife is getting cranky about it. I might transition her to Omni instead of going to a TW rom. It's been a while since I had a Note 2 as an active phone but my wife's OnePlus One is off being repaired (it caught a coffee mug after it fell 3 feet out of a cabinet).
Nope no low volume on my end on your latest build, its loud as hell. I have to turn down the volume just so others around me near by won't hear my conversation. Ouch sorry to hear about the oneplus one that's sucks...
