Each of the three models in the Nike IC putter range is designed to sharpen your focus at address and help you see things more clearly ? all achieved via white ?tri-line? markings on top of the head and along the top edge that stand out against the dark green head and shaft. But do they work? Golf Monthly?s Gear Vault team puts all three models to the test this week.

Check out the Gear Vault again next Wednesday when the GM team take Mizuno?s new MP-600 and MX-560 big sticks for a test drive ? see our exclusive picture gallery now.
