Hi all, I'm currently using a couple of Kingston CF 266X ultimate cards and two Hama 16GB CF bis/up to 30MB/sec cards I would like to buy a couple of 32GB SD cards so that I can backup while shooting weddings mainly. I will be using two cameras any advice would be great please.

I'm not sure I can see the logic in that. If the slowest card is the SD card then buy a fast one surely?

No because the camera cannot utilise a fast SD card. The slot is limited to 177X if I remember correctly. So if you are writing to a fast CF card and a fast SD card the camera defaults to 177X speed. To get the best out of a 5D3 in terms of absolute write speed then only use a CF card. The camera can utilise CF cards up to 160MB/S and there is a benefit to be gained in terms of buffer capacity before FPS slows down from using fast CF cards.
So no point in buying a 95MB/S SD card. Get 30MB/S ones and save a few quid.

177x speed is about 20MB/S I think.
There has been quite a bit of discussion about this. I never used a SD card because its slow. I never write to both cards on any camera as i cannot see the point in my photography.
There is definitely a limiting factor writing to both CF and SD cards at the same time on the 5D3. One way of finding out for sure is to test the write speed to a slow and fast SD card and see if there is a difference.
The buffer on the 5D3 isnt very big and I know folk who have got as little as 6 frames before the FPS started to slowdown when writing to both cards and that was with RAW to CF and large jpeg to the SD card. Givien that the buffer on the 5D3 is around 13 frames something must be going on.
Using faster CF cards on the other hand does have a benefit. From around 17 frames before slowdown on a 60MB/s card to around 24 frames before slowdown on a 160MB/s card.

No, because the 5D3 isn't capable of writing to an SD card at that speed.

No, I never write to both cards. But no one is paying me to take images of their wedding either so writing to both would be a sensible idea, just in case.
I always have 2 cards in the camera. The second card is a 128GB card and I use this to copy the images from the first card to at the end of a session or day.

You definitely will see a difference in tfr speed between a 30Mbps and a 45Mbps card, however... unless you are completely caning the poo out of it (and by that I mean 12-15 frames at high speed continuous, you aren't likely to see an issue.
I shoot to both cards, usually RAW to the CF and large fine Jpeg to the SD - unless it's sport and then it's LF Jpeg to both.
For wedding work I usually shoot RAW to both.

Am I missing the point, isn't the idea of having dual cards so that you write to both cards at the same time?
Would this card suit me?

There is the other option which I do. I use Sandisk cards, never had one fail, so I use the SD slot to write small jpeg. When I was shooting sport, these could be loaded to the ipad for instant slideshow in the clubhouse.
At 2,880 x 1,920 resolution, it's fine for any normal size enlargement or web use and a good option for a failback whilst not affecting the write speed by writing Raw.

That's what I do. RAW to CF and large JPG to SD. And I'm glad I do as a Sandisk SD failed when I was in Tokyo recently. I didn't notice it wasn't being written to until it had missed 20 images.
Sandisk are replacing the 32GB 45MB/s with a 32GB 80MB/s without any questions and FOC.

Not necessarily, an alternate option would be to fill one card then move on to the second. If the idea that you suggest was the preferred option why would Canon have given more than one way of using the second slot?
