I can't say either way about which tartan you wear. Wear the one that you're connected to most profoundly.
But get the heavyweight instead of the standard. The standard is made of the same material as the thrifty. If you want something more "kilty", then a shorn sheep is the only way to go. Wool will look better and more importantly, it will feel more like a kilt.
Hope this helps.
