Hi Echo,

The 910 driver head has a newly designed paint scheme and images are available on our Team Titleist Tour Blog.  The 910 crown has a darker more solid finish than the 905R and the 909.

The release date for the drivers is scheduled for mid-November.  The fairways and hybrids will not be released until early next year.   The detailed specs will be released shortly. 

We did have several PGA Tour players in the AP1's so it is a matter of preference as far as playability.  On the AP2's, yes, you can put the NS pro shaft in them.  I would recommend getting fitted for your irons and trying the shaft out as we have…

I agree with a little of both. I think though with your swing speed tat the x shaft is not a good fit. you might notice you pull or duck hook your shots since the head will remain closed or get closed a little quick for your hands
