I'm in a quandary

[MacMillans son]

There is a difference, somewhere in between what you experience with your 16oz and your lightweight kilts, though not as pronounced. If I were to describe the difference I would say the swish is quicker i.e. shorter in duration. I think you basically have a weight (the material) hanging on a string attached to your waist. The greater weight, once in motion, creates greater inertia, and therefore, if left uninterrupted, a longer swish duration. How's that for over thinking something as simple as 'kilt swish' ?

I think you can have it custom woven in 16oz., and made into a kilt, for around $700-800. Two sources would be the Scottish Tartan Museum gift shop, and Scotweb both are Xmarks advertisers with links at the top of page.

Best of luck with what ever you decide!
