First I am curious whatever came of the original poster Pat Long, it looks like he has never responded back to let us know how he is doing with his RV-4. So Pat if your still hear how are you doing?
Randy said in post #8 that changing elevators changed the pitch feel of his -4, I would just bet that it’s not the skin thickness that made the difference but rather the radius of the trailing edge of the elevator and how flat the skin is ahead or the trailing edge, this is one place that can vary widely from one RV to another giving different pilots of what seems to be the same airframe very different results. I believe a sharper radius will result in the aircraft being heavier in pitch wile a wider trailing edge will make it lighter in pitch, a concave skin ahead of the trailing edge will make it heavier and convex will be lighter.
If wheel landings work for some pilots wile carrying a passenger then stick to what works, no argument here, not trying to change anyone’s mind. Mechanically speaking wheel landings should be harder with the CG aft, the further aft the CG is the more the airplane wants to pitch up when the wheels touch the ground. If all three wheels touch the ground at the same time or the tail wheel touches just ahead of the mains then the airplane can’t pitch up and tends to then stay on the ground. For me it’s a three point every time with a passenger
