Thanks Walter for your insight--as I suspected, studio engineeer and 
I are poles apart on this. I think I'll keep on getting the best 
stereo I can, mix the pieces to my taste, let him choose a channel 
of my stereo and do what he will, then compare the results. I'm sure 
to learn from this interchange.

I'm off to the Big Island for a week of recording, mostly for this 
same project. Most interesting challenge will be to get ambience at 
a Hawaiian adze quarry at 13000 feet on Mauna Kea,where the wind has 
been up to 30-40 knots this past few days, but forecast to drop to 
10 knots. I hope to use the MKH20/SASS for this, but still haven't 
come up with adequate windscreen for high wind, so will likely fall 
back to spaced MKH20's with my home-made zeppelins, which work fine. 
Most interesting sounds high up on Mauna Kea, for this project, are 
the 'Ua'u or Hawaiian Petrel, which nest there.

Aloha,
David
