David, I wore only wool traditional kilts for over 30 years. Then I "branched out" after discovering X Marks. I now have a USAK semi-traditional, and I love it. No, it isn't the same as wool, but I find that I wear my USAK (and my other non-trad. kilts) far more often than my tank. Anyway, that's my experience; I am totally happy with my USAK.
