Dura ace aero hub

Hi
I'm looking to buy a pair of dura ace hubs (F 24H, R 28H). It's for a handbuilt with sapim cx ray spokes.

I am in doubt about which model to buy, its either (front hub, as example, same applies to rear hub)
Shimano Dura Ace HB-9000 Front Wheel Hub
or
Shimano Dura Ace HB-9000 Front Wheel Hub for Aero Spokes

What is the difference?

Thanks,
Erik

The one for aero spokes will have slotted holes to be used in conjunction with large bladed spokes, like DT Aero Comp or Aero Speed or Sapim CX. There is no need for that with Sapim CX Ray, as they are only 2.1 mm wide and fit through standard holes

Precise and to the point answer. Thanks a lot!
