Canon 1D MKIII CF to SD Adapter

HI All,
Has anyone used a CF to SD adapter in the CF slot of a 1D MKIII? Or a CF to micro SD?
If so which one did you use and did it have any impact on the performance?

Yes I have used a Jobo CF card adapter to use an SD Card in a 7D and 1D3.
And in some cases i still do with the 7D.
Shoot JPG to SD and later put the SD inside a RavPower FileHub so others can copy pictures to their mobile device.

I even tried an Eye-Fi Pro card, but that was not a great succes.

Both in the 7D and 1D3 the performance of an SD was less then when I used a CF card.
I never had any problem using it. Never lost a picture on SD.

Never used one, but mk3 has dual slots so I not sure why you would need to o this? Cant imagine it would slow the read/write beyond the crawl it is anyway.
