Would it be possible to stack two 1.4 TCIIE's? Anybody tried it or know that it will or won't work? 2.8 result? I've heard you can't do a 1.4 and 1.7 together, but can do a 1.4 and a 2.0 in theory. (may require some mod?) But not sure about 2 1.4's. Not saying the image quality would be decent, that's a whole nuther subject. But if you did it, what quality did you get? (if it can be done) thanks.
