nope, try again.
Tiger is not required to use any Nike clubs, by contract.
i will also assure you that, at The Oven, there are hundreds of different combinations of drivers heads/shafts that have all been tried. this includes non-Nike products. Tiger continues to go back to the Nike VR driver.
you state that his "driving has ever [sic] been good with Nike drivers ". this is not true, either. his driving has never been the strongest part of his game. it's always been his approach game. for years, Tiger was much better than the field in proximity to the hole.
