I'm borrowing a 1Dx from CPS along with the WFT unit for an advertising shoot I have in November. I hate tethering (not my style), and have toyed with the Eye-Fi cards, etc. If at all possible, my agency client would love me to shoot and at least send low res JPEGs to an iPad for the end client to view as I shoot, since before now, they've always shot in the studio (versus location) and are "anxious" about the shoot. (I guess after shooting for 36-years, saying "trust me" no longer suffices.

)
Has anyone had experience with the 1Dx using the WTF-6 sent ad hoc to an iPad? Is it even possible? Was it slow as a dog? I assume I'd have to use dual cards for RAW and JPEG to send just JPEGs. Anyway, any comments would be most welcome. Thanks.
