Ah, sorry, it was for Mr. Lunceford.
I have not tried the CM700 on choirs, although I rarely have to mic large groups of singers. It is good to know, in case that need arises. I have 8 CM700 mics but I have pretty much put them into retirement since I discovered the Beyerdynamic M201TG.
I bought a pair of the M201TG and started moving them around and trying them on many different instruments. I ended buying 10 of them, replacing the Crown, EV NDYMs, and SM57s.
As a side note, I purchased an Earthworks Vocal mic and it came with a K&M mic clip, with an Earthworks sticker covering the K&M logo.
