Even experienced rugby players like Jerome Kaino feel the extra bite when they visit the Bulls' home cauldron.
The vagaries of the Super 15 draw meant the Blues ducked that duel last year but they have to get past the Bulls this weekend to halt their ropey start to the series.
In contrast the Bulls, under new looseforward captain Pierre Spies, began with a strong win against the Sharks and then opened the throttle against the Cheetahs.
"The Bulls have been on fire, but our guys will be focused on getting the job done," Kaino said. "The Bulls have been pretty good despite losing a lot of their experienced players. The two locks have slotted straight in where Victor Matfield and Bakkies Botha were."
Others missing from the Bulls' roster this season are halfback Fourie du Preez and forwards such as Danie Rossouw, Guthro Steenkaamp, Derrick Kuun and Gary Botha, while new halfback Francois Hougaard is suspended this round.
