The past year has been a wonderful experience as the Open champion. The best part has been feeling the satisfaction from that huge win. Returning to St. Andrews to defend will be awesome!
For the Old Course, I will probably go to a 54° wedge in place of the 52° and 56°, and add a 3-iron and four-iron in place of my current 3-iron [which plays between a typical 3- and 4-iron]. On a links course, spin and wedge control mean less than imagination and trajectory, so I'll give up the extra wedge in favor of the flexibility in the long irons.
And I always use a lower-spinning ball, Nike's One Tour D, which works well in the cold and wind of the Open links courses.
FAIRWAY WOOD: Nike SQ II (15°) with a UST Mamiya ATTAS 7 X shaft
PUTTER: Nike Method 001
BALL: Nike ONE Tour D
Sandwich: My trainer Chris Noss makes a mean PB&J! Seriously, he makes one for every round, with the healthiest ingredients. I usually eat half per nine holes.
Range Finder: I feel naked if I leave it at home. I even carry a spare battery in case it goes dead. On Tour, my caddie Frank Williams and I use it to chart yardages, especially uphill and downhill adjustments.
Tees and markers: These tees create less friction at impact and they break less often than wooden ones. I don't have any lucky markers, but a fan I see occasionally has given me some awesome collectible coins, like this 1864 two-cent piece (lower left) and this 1931 dime (top right).
Drink Mix: I carry Amino Vital, which mixes with water to help hydration and focus, and Living Fuel bars, which are packed with healthy ingredients."
