A wide band O2 sensor is the way to go. I use an Innovate LM1 and LM3, thus
having data logging capability. I don't keep the O2 sensor in all the time.
I used it, logged it, made adjustments as needed then took the system out. I
noted what the EGTs were at WOT on a long straight and if readings are off
then I know something is not right and make mixture adjustments as needed.
Long term use of an O2 sensor with leaded fuel will ruin the sensor.

I had inconsistent readings when I had mine 6 inches from the flange. Sam
Halkias told me to move them 6 inches from the valve and that corrected my
problems. I think I am going to try a wide band O2 sensor this year to get
another picture of what my mixture is like.
