If I get what you are trying to say its that the XT wont let you shoot fast 1/200 with a flash?
If thats what you are saying then that should be right, your sync speed is 1/200 so any faster and your camera wont catch it. (I think, still learning with flashes) Not sure if thats what you were looking for though.
