I've got two SWK Standards in BW and MacLaren and use them as my hiking kilts. I had them hemmed to 22" by a tailor out here not for your reason but because I'm short in stature (fireplug shaped). They are gerat for wear and have held up so far. Washed and the pleats needed some touching up but no biggie. When you do go the PV or, even better, the wool route, the kilt will be custom made and the rubbing on the back of the leg should go away. A kilt that is too long will do that to the back of the leg.
