Thanks all for the responses.

Sydney has a moderate to hot climate. We average 35C peaks in the summer and 10C in the winter. It doesn't snow.

I have four kilts: a PV Neokilt, a cotton (!) SportsKilt, a "denim" Union Kilt and a wool SWK. I love the Union Kilt because it has pockets, but it's looking a bit loved and I'm not really happy with the pleating. The Neokilt is, unfortunately, now too small, but I loved it for the time I could fit in it. The Sportskilt is for very warm days only, I have to say (think NYC in July), but is very comfortable.

My black-shadow SWK heavyweight is the heaviest kilt I own and SnowBear's numbers match my own. So it's probably an 8-yard 13oz. That would make a 16-oz 5 yard about the same weight. I like the hang and fit of the SWK but I don't think it's worsted wool.

I was eyeing up Burnett's and Struth Casual because the price is nice, but there was another maker I can't find now who also uses the same fabric. And their 8-yarders are a better price. If I can only find them again...
