It's like having to choose between two top four-wheel drives. Both big and powerful and able to carry a heavy load. They're also highly sought-after and regarded as among the best in their class; just like Bismarck du Plessis and Adriaan Strauss.
There's no doubting these two Springbok hookers are up there with the best No2s in the world.
Heyneke Meyer must at times wonder what he's done wrong or right - to be in the position he finds himself.
Only this last weekend, Strauss, who started against Australia, played one of his best tests for the Boks before being replaced by du Plessis early in the second half and this weekend when the All Blacks visit Ellis Park for the Rugby Championship showdown the roles will be reversed. Du Plessis will start and Strauss will warm the bench.
The rivalry for the No2 jersey has brought out the best in the two former Grey College pupils, with the hunger to play so much greater now neither is guaranteed a starting spot.
