I remember reading briefly about the HRC routing. What's the difference and advantage? Do you have a link otherwise?

From memory benny the water comes in the top rad on the top right hand side, exits the top rad on its lower left side, so the water has to pass from right to left. It then enters the bottom rad on its top left corner and exits on the lower right side, so again the water has to pass threw the radiator but left to right this time.

The theory behind it is the water spends longer passing threw the radiators so should have a better chance of cooling.
