One thing that I have always been impressed with is knowledge that is held by others. As time goes on, and one learns more, eventually one is sufficiently educated such that one is able to recognize the true expertise that is held by others amongst us.

Some time ago, Matt Newsome explained to me the several advantages of 16 oz over 13 oz, and I can say that he is correct. In the end, 16 oz is superior, the only apparent downside is that it is more expensive. But it isn't much more expensive, and that is why all of my kilts (but one) are 16 oz.
