I owned a Christen Eagle and it was awesome. A good friend had an S-2A. I like the Eagle much more than the Pitts as long as you can live with the limitations of it being experimantal. ie not instructing in it etc. My Christen Eagle was about 5 knots faster than the Pitts S-2A, the cockpit is much more comfortable with better visibility. Hardest plane I have ever landed. Takes a little getting used to doing the rudder dance. I think the Pitts may be a touch easier to land since it has that bungee cord type suspension on the front gear. It gives a little more. I got a book on doing aerobatics in the Pitts and taught myself how to do most maneuvers. If you put the throttles at idle and let go of everything it will come out of most any out of control scenario by itself. I just flew the plane for fun and never had any desire to compete in aerobatics. By yourself with a half tank of gas it is a lot of fun. A harness with the ratchett on the waste belt is highly recommended if you plan on doing much negative stuff. I bought mine already built. Cheaper and didn't have to wait to finish building it. Just need somebody that knows what to look for when buying a built one. Being experimental, there are varying levels of build quality out there.
