Thanks for your input, I'll definately try out some of your ideas. 
Since my original post I've had ample opportunity to beat the hell 
out of my 410. My current favourite trick is to use a 410 in the 
feedback loop of a 420 to enhance the Q of the bandpass filters.

"some audio signal" feeds 420 IN1
420 OUT feeds 410 IN
410 MIX OUT feeds 420 IN2

Set the 420 to LP mode, tweak the 420 INs, RES, and FREQ as necessary 
to get very narrow Q from the 410. A great way to extract specific 
bands from a pink noise source.
