Usually I get the mark appearing over 1/4-1/2 of the spinner. I had to try different spots by trial and error to improve the balance after that.

Any ideas on which softer tube material could I use to reduce the sensitivity?

You can reduce sensitivity by reducing the preload.

When you get the balancer new it takes a press on the beam to get both magnets to engage.
If you reduce tube length to the point that the axle just clicks into place you will see a reduction in sensitivity.

Make sure both sensors have contact with the tubing too short will stop the unit working properly.
