From what I have seen over the years everyone has their own “style” so to speak. It just comes naturally from years of practice. I have seen many try to adopt the stance/style of the experts and concentrate too much on stance and not enough on what the airplane is doing. I have been kidded about my gyrations out in the circle but I have no idea what I am doing out there, my concentration is on the airplane, I think my stance came about from years of practicing, focusing on the flight, the maneuvers, some of the best practice sessions and competition flights have been where my intensity level was so high that everything else is blocked out, there is a zone that is reached. It is a cool feeling when everything is working right.
