I wish we'd had your U-67 to listen to, but we came up with an impressive collection of mics nonetheless (all 49 of them). If you (or anyone else) want to see it, I just posted a picture of all the mics at my web site. It is suitable for framing (or desktop-ing, if you prefer). And of course, if you want to hear them, the CD ships in March. Just let me know.
