I probably won't be much help here. I use W&N 100% cotton. I personally prefer natural fibers particularly in quilts. And everyone that I've gifted the quilts to comment on how warm they are. I'd love to try silk batting at some point but it's really spendy and not locally available. Since I have a whole roll of W&N, it will probably be a while before I make my way to the silk. Have never tried Hobbs batting. Heard good things about it, just not readily available locally.
