I have Kai'li shafts in my 910F as well as all 3 910H's. My one issue I have with these clubs is that they all tend to have a lower flight than I'd like. I know when I was fitted for my 910D3, the Kai'li was quickly ruled out. The RIP that is in my D3 is incredible and I'm absolutely pounding the driver with high, straight shots that are easily 20 yards better than the R7 it replaced.
While distance is great, I'd like to get a similar flight out of both my F & H clubs. Was the Kai'li not my best choice?
