I use W&N but I also hand quilt. Most people think the W&N is just too dense for hand quilting but I have no issue with it. It's very low loft, 100% cotton and very warm. Reguires quilting 8-10 in. but I've quilted it more densely than that and not had an issue. I've also machine quilted it for charity quilts and have had no issues.
I'd love to try a silk batt one day. Fondled some at Lancaster a couple of years ago and it is divine. You'd have to do some searching for how it machine quilts if that is your plan.
