Hi Rob,

That's a good idea, I will start taking screen shots of settings and curve so I 
can share them visually.

My approach is typically far less complex than yours: I don't typically eq 
channels independently, and though I find narrow stabs to be effective 
sometimes, I usually apply a flowing curve that highlights some of the most 
interesting aspects, without too exaggerated of slope on the transitions,and 
leave it at that. You have shared some great ideas for eq that I hope to 
explore when I get necessary software and find time.

I allow for a lot of creative experimentation in my eq approach. Sometimes I 
put a low spot around 1K to distance the composition from the realm of human 
conversion. Sometimes I imagine fault block mountains with tilted slabs and 
escarpments and each range at a height to allow view of the features beyond. Or 
a similar effect with an image of the Pacific ocean with large, each break 
releasing energy to a gentle lapping at the shore.  Usually though I start by 
leaving the body as wide and flat as possible and roll the high Hz enough to 
ease the hiss into the range of natural possibilities. If i need to attenuate 
low frequencies above 30Hz I sometimes follow that up with slightly exaggerated 
berm above it to keep a sense of strong foundation. Once top and bottom are 
established, I play around with the stuff between until I find the sound I am 
after. 

I cannot comment on unresponsiveness of the NT1A to eq boosts between 80-300Hz 
as I have not had a chance to compared it with many other mics, though I will 
definitely listen for that limitation.
