Welcome from the Windy city. I think that a kilt makes an extreme amount of sense for a curler. Talk about ease of movement!

And you could do much worse than an SWK Heavyweight. I have the HW in the Weathered Lamont tartan (wool) and also the older style shadow tartan HW in acrylic. I prefer the wool. Nothing with the acrylic, just my preference. You might also want to consider a USAK. Their PV kilts are an excellent value and do not have some of the issues that an acrylic has (pilling).
