Thanks for the replies.

I bought a prop & spinner already drilled for a 3W/DA.

Now some solid advice regarding filling the 3W/DA holes in the prop that are now not needed.

Will filling these holes be beneficial?

Is the hole filling with epoxy only appropriate for composite props only.

The prop I bought is a Menz wood. Which makes the most sense

1) leave the holes - do nothing
2) Fill the holes with epoxy
3) Epoxy in dowels to fill the holes

Thanks for the guidance
