Martin, Tony, I've read many times (and seen with my own eyes on my Canon FS4000) that the green channel is the one with least noise and best detail (therefore my workflow for B&W, including chromogenic, is to pick the green channel from Vuescan raw files). I understand that keeping also R and B channels should somehow "average out" grain, but I'm also sure this will increase noise (especially from the blue channel) so much that I doubt it will give better scans. Anyway, I'll give this a try and see what happens...
