Corner treatment -- PZCs a sure thing?

I'm looking for a set of room upper corner treatments for my living room. The upper corners probably are the only places in that space where I can use audio-specific treatments. The triangular pillow-type traps seem like a pretty sure thing; it sounds like only good can come from reducing the amount of energy being megaphoned out of those corners. I'm not so sure about the tunable pressure-zone controller devices (Michael Green). Are they as versatile and sure to be helpful as the pillow traps? Can anyone describe the comparative effects of these two approaches in their room and system?

Hi Jayboard!
I only noticed your question today.
If you're in doubt about the PZCs as corner treatment (who's gonna blame you for that?) you could try to build your own, first.

Here are some pictures as to give you an idea as how to imitate them:

Now, the wooden face plate is something very important!
Standard PZCs have cherry face plates, but you can choose any wood of your likings. Check out some guitar building sites for inspiration.
Use very thin layers of VARATHANE to treat the wood;
making it hard on the outside but soft on the inside of the wood panel!
Then proceed like this:

Make sure there are washers between the face plate and the frame: http://www.htforum.nl/yabbse/index.php?action=dlattach;topic=47451.0;attach=32147;image
Tuning the face plate can be accomplished by attaching a tuning bolt to the front bracket and the face plate: http://www.htforum.nl/yabbse/index.php?action=dlattach;topic=47451.0;attach=32148;image

Good luck!

Kind regards,
Roy.
