It's Driver World Cup time again and this week we're putting the Callaway Hyper X against the Nike Sumo 5900 driver.
The two 2008 drivers form part of this year's knockout competition, which sees eight of next year's best drivers pitted against each other to find out which one is best.
To help find out we have employed three golfers of varying abilities who will each put every one through its paces before debating which one from every pair goes through to the next round.
So far we've had two of our four round one matches and the Mizuno MP600, Cobra L4V and Ping G10 have won through to the semi finals.
So which of today's pairing will join them? Scroll down and watch the video to find out - and log on next Friday to see the first of our semi finals.
