Gogofo, the two of you are not in piecing right now, correct? She has to make the right decision first. She says she wants to work on the M but doesn't know how? Sounds like a weak excuse. With all the information available on the market, I believe she could at least read about "how" to work on it.
It is not about what you feel should work in your M. It is about doing the work that gets the right results. Do what works!
