Rory vs. Louis: Who has the sweetest swing of them all?

'Both have great attributes, and they're quite different,' said Adam Scott, whose swing is also considered one of the best on Tour. 'I'll say Rory only because I think he's going to be able to hit a few more kinds of shots, but Louis' swing is beautiful.'

Oosthuizen, the sweet-swinging South African, has a simple and compact swing, which many consider the most fundamentally sound on the Tour.

Jim Furyk, known for his unconventional action, opted to stay neutral, but he spoke of his appreciation for both swings.

'Louis has power, but he's also extremely rhythmic,' said Furyk. 'He hits the ball both ways. I don't know if there's (a swing) fundamentally better in the world.

'Rory hits the ball right-to-left, and I don't see him cut the ball much, but he's more explosive and has the ability to really light it up when he gets hot.'
