I would like to say that I've used CBBE since v2.0 way back when, and I truly can't imagine using any other body mod. I was saddened when HGEC was never converted over to FO3 back in the day, and to hear that CBBE is coming to FO4 is truly wonderful. Although, I must admit that 21K Poly count seems a bit high. I hope you'll have a low poly version available as well? (closer to 7k or 9k?) I really enjoy building settlements with the object limiter off, and I'm just afraid that super high poly bodies will gum up the works.
