Derek:

I've one of those as well, and a fine kilt it is. However, I notice that the sixteen ounce Leatherneck tartan I picked up is much more vibrant, the colors really "pop" out at you. In comparison, the 13 ounce Rocky stitched up for me seems much more muted.

If you have downloaded BarbT and Matt Newsome's update on box pleated kilts, you can see one of Barbara Tewksbury's box pleated kilts in the 16 ounce Leatherneck (made for a blood brother of mine), which shows the difference.
