I just completed the Service bulletin on my 6A, I am not satisfied how it turned out. I have about 600 hours on my 6A, with minor shimmy problems. I had used gear leg Stiffener on the nose gear. After the mod I removed the stiffener and the shimmy is more than I like. I use 31 PSI in the tire and use about 20 pounds of pull on the break out force. Any good suggestions on how to make it smoother. I am about ready to replace the nose tire and install the stiffeners back. I sure wish I had my old 6 with the nose wheel in the back. Any help appreciated
