Ron,

I have a USAK casual and semi-trad, and also a SK. However, my SK is the older style without the pleats sewn down, no belt loops, fringe, etc., so can't really comment on the new style. I have not checked the prices lately, but doesn't the SK with all the options come to about the same price as a USAK casual? If so, based on the quality and fabric, I would go with the USAK. I am wearing my Ireland's National USAK casual again today and I really love this kilt. Easy to care for, hard to wrinkle, just throw it into the wash. What more can I say?
