I think if we go back through the years and reread your post's we will find many excuses why you did not buy a 72 along time ago , this mower will more than likely be the same.
I don't believe you will find a reason I specified why I never bought a 72. I guess with your background in physics, you do realize that 72 is only 6" wider than the 66 I've been running for the past six years, and I've run several 72's through the years while never seeing any real difference in maneuverability.
