I don't know what it is, but when tiger tinkers or changes equipment, it speaks volumes to me that he'd trust that new piece of equipment to perform. I have a feeling his standards and expectations are pretty high.
Haven't thought of that before but totally agree. He's not a mad scientist or a detached-whatever-type. My sense is that he is very detailed and thoroughly evaluates equipment for highly specific purposes. This is an interesting time for Tiger. He's competitive again AND the door is more open to Tiger behind the scenes. I also love Tiger the golf mentor. RIP the old Tiger. Long live the new Tiger.
