David,
The MKH80 is just fine, thanks. It must have been hit, or dropped (there is a dent in the grid as described), but performance is on a par with our other two MKH80s (one of which made a 3.5m drop, and unluckily protected the stand on impact (not the other way around

, but after cosmetic surgery, the eletronics and capsule measured out perfect at Sennheiser Benelux) - those are solid mics (not the switches mind you ...).
Now we can fly a decca tree of MKH80s - hmmmm, should be easier to position
Did you bid on the MKH30 ?
Concerning the AEA mic stand, we bought an AEA13 HDV, with 13' boom and an optional extension (for those 12m high organ recordings), and have never been happier to put a mic in front of an orchestra. This one wont fall over, but it is fairly expensive.
