Thanks for the response, TrekkieGrrrl... I do have UTC, so I can do the conversions, and I don't foresee the navels being a problem. I think there are separate Hybrid programs for V4 and M4, however; the "hybrid" part seems to be that there's no separate Masker or Eyer program for the 4th gen models.

Again, thanks for the info; I'm a fan of your work!
