What kind plywood should I get to sheath - sheathe my house?

This topic is available here on The Repair-Place forum
I am planning on putting on a little addition to my house. I'm building it with 2 x 6 studs, and I will need sheathing. What type of plywood should I put on the outside for to sheathe my house?
What thickness should I use?
I would use 1/2" cdx exterior grade plywood on all the walls. You could use osb sheathing (oriented strand board) but I have used it in the past and prefer regular cdx plywood. osb is less expensive than plywood and could be the determining factor.
