I'll just add my two cents worth here...mind you my words are not golden...

A great friend of mine told me when I was preparing to buy my first kilt that anyone with experience can literally see the difference between a 13 ounce kilt and a 16 ounce kilt. And the 16 ounce kilt will hang, and move, and, just generally, look better.

I think he was right.

FWIW...
