George,

This is not meant as a critique, just a clarification...

When you say "*Opinion, based on owning a HW Stillwater*", do you mean that you are under the impression that the stillwater is PV?

What Poly Viscose kilt do you own (from what company)?

To the best of my knowledged, Jerry's HW kilts are 100% wool (not SCOTTISH wool, but wool just the same)
