Hi Diesel,
I’m not sure if you’ve read these but there is more information about wool toppers and how they compare to latex toppers in post #8 here and the posts it links to that may be helpful which also includes a link to a list of some of the better sources for wool toppers I’m aware of.
There is also more information about choosing a topper in post #2 here and the topper guidelines it links to that can help you use your sleeping experience as a reference point and guideline for choosing the type, thickness, and firmness for a topper that has the least possible risk and the best chance for success. It also includes a link to a list of some of the better online sources for toppers I’m aware of as well.
