I am going to take a plunge and get a 8 yard kilt in my clan tartan and was wonder besides being heavier does the 16 have better attributes over the 13 oz?

Maybe things like looks,
holds shape better
swings better.

I am going for a well dress look might even get a Prince Charlie, and go with the idea that I can always dress it down.

I do live in Texas but I am pretty acclimated to the heat as I ride a motorcycle all year long with full gear and a full face helmet.
