Is 11 oz tartan a good weight for a kilt?

[S Mitchell]

I do have 2 16 oz 8 yd kilts. And I know that's the way to go.

But for a pub and play kilt that's really my question. P/V comes in 11 oz from what I've seen. So why P/V over wool of the same weight or vise versa.

I have a USA Kilts casual and I've very much come to appreciate how durable the pleats are and how wrinkle resistant it is plus it's machine washable.
