Yeah, sorry about all the goofing off. I know it can get confusing... I remember back when I was trying to get this all sorted out myself.
Now, I'm not sure what you mean by "TTA" but most of the stock out there now should be v3.0. And I must say, V3.0 is a VERY high quality light.
Oh, did you mean TTS? Texas Tactical Supply? You'd have to email or call William directly to confirm what he'll be shipping.
Feel free to ask any more questions, and I'll try to be as straight forward as I can be... provided you catch me before happy hour each day.
