Anthanasius, it would be nice to have just one all setting to cover most of your render needs.  However, you are aware that different scenes require different render approaches.  And finding the right settings can be very time consuming.  I never said that BB's recommendations were Gospel, but they are good starting point guidelines to find what is best for your needs.  LOL, believe me, I have to think very hard and long about the work involved changing nodes and modifying Gc when committing time to a personal project.  I was spoiled by PoserPro and I can't wait until the 2010 version is released officially.
