I love the PDR.
Here's my line through the esses and "toilet bowl". I've found that entering the esses tight lets be carry much more speed through the previous corner. I often pick up several car lengths on pretty much everyone through here. Also, pinching the exit of the bowl just a little lets me straighten out the bump and get back to WOT before the back straight, and I end up carrying much more speed through that straight as a result.
