Good pics zort. IMO the best body position is the one that allows you to get off the bike as much as possible to decrease lean angle and/or increase cornerspeed while at the same time allowing you personally to remain comfortable, loose, and in tune with what the bike is doing...
That being said the faster you get, the more like Jason's photo you need to look like. Obviously he's fucking fast... and look at his body positioning.
At this point mine is most like Zort's and Mark's.
Here is a video capture of me. This is actually a left hand turn so I mirrored the image just to follow the norm of the four pictures Kurt posted...:
edit: rotated it to be flat:
