Loud wooden pole

This winter i refinished my pole. It is a 10ft, 1 1/2 inch diameter softwood pole. A "HomeDePole"

For the last several years I'd used it without a shoe. After trimming the rough end and refinishing I attached a copper cap.



It worked great, gripping the rock well. But I was surprised how much louder it was. On rock you can hear the shoe strike resonate through the pole.

Does anyone have a suggestion for a quieter shoe? If nothing else I'll just splice a few inches of oak dowl on the end.

If you can get the cap off again, a rubber washer between wood and metal may do the trick.
