TDM, what cases do you use D moves for?
As Marcel said, keyhole. I use it for both edges and corners. You can easily turn 8-move cases into 5-move ones.
e.g. setup with D R U R' D', solving the FR pair:
Usual alg: U2 F' R U R' U' R' F R
Keyhole: D R U' R' D'
And of course, if you were looking at the FL pair, that alg is much faster than U' L' U' L U2 L' U' L or U L' U2 L U' L' U' L.

What about
D R U R' D' R U' R'?

I've played around with this before.
