I use these. I researched it extensively first to ensure conformity and then I stocked up.  Great value if you can find them and absolutely no performance difference. 

Congrats, you're going to love them. The fitters are awesome guys. Wish I had the time to use mine more often this year. 

Mark,

Glad to hear that you're enjoying your Titleist equipment. Accuracy, in my opinion, is much more important than distance. Now, the 910's have great distance and are very accurate it terms of your shot dispersion. 

sorry, i guess i should specify that it is a diamana kai'li 65g shaft.
