As far as I can tell, the RTs are recorded with very little processing, in order to leave as much choice as possible open to the user.

Your method of working seems to me to be very logical and efficient and I wouldn't see any reason to change it.

As far as getting your recorded tracks to sound like the RTs, I think you answered your own question! Other than that, just watch the EQ to make sure your own tracks don't end up too bright or too dull compared to the RTs.
