You said it better than I did. Thank you.The only ones that are officially V2 are the MTCH 212 and the MES 412 OS, because those two officially replaced older cab packs with a Version 2. But as Justin was saying, it's really more of an iterative process where each pack is a learning experience and his process gets slightly more refined than the last. "The V2 Process" is really just "the updated process as it's shaped up around the v2 packs compared to the years old process the original versions used". For that reason, his more recent packs will be the ones using the more recent approach. This 5153, the ORNG, The FDMN, the T75 are all newer packs if my memory serves, plus the 2 V2 packs obviously.
