Nothing snobbish about preferring wool. To me, it's like preferring leather shoes over those horrid fake-leather ones. If you're going to spend the money on something you want to wear and look nice in, it's worth it to get the "real thing", not an imitation.

My first kilt was PV. But once I got a real wool kilt, I couldn't go back to wearing PV. It was just too light and didn't feel the same. PV isn't a "cooler" fabric, despite many claims to the contrary. Wool is actually very breathable. The main factor in a kilt's heat-trapping properties is the amount of material used. I wear wool kilts all year round, even in the South Texas summer heat.

The only advantage I can see to buying PV is the lower cost. But if you have the budget for wool, my personal opinion is that you'll be better off going that way.
