Have both, prefer Injection Magik by far. It's much more flexible, does all the same stuff only better. And Injection Magik doesn't insist on using only V3 files even when I've told it to do a Michael or Freak character. The catch is getting it right now. It was one of the products which was sold to DAZ, and they haven't put it out. It sounds like maybe they're changing IPB to be more like IM?
