I concur with Jake. All of my other flights at 125' saw only a very slow drift. My EZB flight (125 to 130') needed only one or two steers. Same with my other F1D flights.
Next time, I'll put up a mylar balloon to see how much drift there is at different heights.
Overall, I would say that the new Kibbie Dome is docile. The air is consistent. The prop turns about 10% faster than Johnson City.
