I recently purchased a 910D2, 9.5 with a Kai'li 65 shaft. This is the combo recommended by the salesman at Golf-smith. My old driver is a 983K with a YS-6 .335 S shaft. I love the 983, and so far don't like the 910. For lack of a better term, it wobbles at impact, and it doesn't have the same sweet spot feeling. Of the different shafts available, which is most similar to the YS-6?
Thanks, Jim
