I found the Geddes book to be very helpful. Fairly concise and mentions specific products he's used that work well, which was exactly what I needed.
Anyway, I've decided to do the resilient channels and was relieved my contractor has actually worked with them (I think mainly in commercial applications). However he's advocating using a single layer of drywall into the channels, and then a soundboard between the channels and the studs. My bias is to use two layers of drywall damped by liquid nails or green glue into the channels and the channels attached directly to the studs. Any thoughts on this? Thanks yet again for any thoughts.
