Yup; excellent thread. I have to agree that placement is paramount. A great mic in the wrong spot is NG. I have lots of evidence on my HD to support this opinion. I bought very good mics (Schoeps and DPA; card and omni) and now I can blame only myself for a bad take. I was trying the ORTF with omni flankers, but that only works when the room is good. In a bad room/wrong spot the flankers only make it worse.
So I am back to mostly ORTF and moving the setup a little one way and then the other to get it right, some of the time. I am often disappointed at this, but have been doing it for less than a year. I have gotten some good recordings and am getting more now than before. But it is always practice, practice, practice. Or, the Jesuit motto of learning: "Repititio, repititio, repititio."
Keep those informative and reinforcing threads going!
Cheers
