I've used Sonar with a couple of Ff800's and ADATs. Worked well along with an HP i7 laptop.
I'm still using the same laptop but now have a Presonus SL2442 mixer. The NLT issue is it's limited to 48khz sampling rate. When I want better resolution for say orchestral r predominantly mic'd performances then I take the direct outs and feed them to the ff800s to get at least 96khz.
I setup templates with all routing already taken care of within Sonar so it makes it quick. Using the SL2442 and having control of the live mix as well as recording is very easy and gives you full control.
For straight recording RMEs digicheck is great as well. I've had mixed results using Presonus Capture so don't use it often. It could do with another patch to take care of a few instabilities
