Replying to Memory cards

What is a great memory card setup for a T3i? I've been looking at the SanDisk 16GB Extreme Pro 280Mb/s card but I'm not sure if that card has the dual layer tabs. Could a T3i even handle that as far as taking all that it has to offer. I;m looking at that card because I really don't want to upgrade camera bodies yet so I'd like a very fast card so I can bump the bit rate up using magic lantern.

I know a decent amount about memory cards but I don't know much about increasing bit rate, dual layer cards, or if the t3i has a dual layer reader.

All help is appreciated, just trying to make the camera last another year, quality wise.
