I have all three weights in hand sewns. For me its been what the tartan was available in. But when I had a choice of the 13 or the 16 for the RAF tartan kilt I leaped at the 16 ounce.

16 ounce is my favorite...just because it "is."

But since when I wear a kilt I've chosen it for its tartan, not its weight, the weight doesn't much matter to me.

My first hand sewn was in 11 ounce because that's all the tartan came in. I was thrilled with the kilt. When I finally bought a 16 ounce kilt the difference was obvious and wonderful - but that didn't detract at all from wearing the 11 ounce, because I love the tartan the 11 ounce is done in.

Make sense?
