Even though I use the R11 driver, and callaways most of the times, and even without spikes or freezes. I would say about 2 out of 10 shots most of the time. Its just way too fast for me. I often click when I'm near the outer bars on the ding because of this. I know there are players who can hit it regularly, so they have an small advantage straight away. I would love to see a driver that has a much slower swing speed for us mere mortals who struggle with this. Not for everyone, I know. But for those who are happy with a faster swing meter, then this would not be a problem for them, and they wouldn't need to go buy another driver. Just a thought.
