[Fot] Brembo slotted disk "handedness"?

[J.C. Hassall]

I'm about to install a set of slotted disks on my TR4.  While the 
boxes carry the same part number, the rotors are clearly "handed" 
(slots CW on one, CCW on the other).  While I doubt that slot 
direction makes a big difference, seems to me that slots "scooping" 
forward (CW facing the RH side), might pull more cooling air into the assembly.

What says the List?
