Best rock to use for drainage ?

I have a drain pipe going from my patio to a big hole in the ground away from the house (we don't get a lot of rain here so I figured a hole like this should do). I want to fill the hole before I cover it with dirt. What's the best type of rock to use for this purpose...big, small, round, square...etc. ?

I would fill the hole with big (2 inch) rock to within 8 inches of the top then put 2 layers of landscape fabric then the dirt. There needs to be room for the water so small rock will not work.
