I have two four yard Locharron casuals and a five yard made by Alexis Malcolm. They are all comfortable to wear. The difference? In the five yard, the pleats are deeper and fewer of them (but it is very nicely pleated to sett and the sett determines the number and depth, I understand). I think I detect a little more "swing" in the five yard (though it's hard to tell when you are wearing it and not seeing it.) I have never worn a tank so I cannot comment, but the info, Matt, on your web site, is quite convincing about both the historicity of the "less material" kilt and the user-friendly-ness. As you will be making a box-pleat for me later, I wonder what the "swing" is like compared to the knife-pleated kilt?
Thanks.
