When you place your order for your 910 driver,  if  you have a specific swingweight request, you should order it with that swingweight.   Otherwise they will build to a standard swingweight which is D1-D4 depending on the shaft.  

The bezel weight kits are for swingweight only - they do not affect ball flight.  If you want to play with swingweights and do not order your club with a specific swingweight, the kits are available for sale at all Titleist retailers.
