The USA kilt site looks good. I too would be interested in the differences between the casual and the semi-traditional. It would be nice if there was a single picture of each one, or some way to see what the differences are beween them (especially amount of fabric). Does the Semi-tradition have the traditional rise and the casual is design to be worn lower? Can you get the higher rise but still opt for a velcro closure? These are things that came to mind when i was looking at PV choices.

Cheers
