Hmm, interesting. Reading up on it, it seems this mainly changes current stock parts. What is the retro pack/small SRB it adds? And how intrusive are the changes to stock parts, especially if I'm already running with a bunch of other parts packs? Hmm, like I mentioned I was looking for something other than FASA, as that is the only one I've found so far. I'm not super keen on adding a bunch of parts I'm not going to be using (I'm not too into using actual replica bits unless I have too, at least for now). I'm not at this point interested in going for procedural parts and tweakscale and similar, although I may well be in the future. Still, thanks for the suggestion.
