Hi Blu!

Well, first of all, an 11oz worsted is generally considered more suitable for women's and children's wear, than for men's. If you were resident much further south, I'd say you might get away with an 11oz but, being where you are, my advice would be to opt for a 13oz. There will be a difference, or several differences. Certainly the hang will not be as good with the 11oz - nor will the vital 'swing factor' (the heavier the weight, the better the swing!).

I do not understand when you say that Maple Leaf is available only in 11oz! One of my kilts is in that fine tartan and it is in 16oz!!

You appear to be concerned also about what tartans can be worn by whom. The only truly 'closed' tartan is the Balmoral, which you would not be able to buy anyway, since it is reserved exclusively for members of The Royal Family. All other tartans are 'open' and may be worn by anyone, although you might like to choose one to which you have some link, however tenuous. I have eleven tartan kilts and Breacans, but I have a family connection to only two of them, in the Gunn tartan. The others I chose for no other reason than that I liked them!

Personally, I think you should really put that order on hold until you have thought a little more about things.
