I really like wool (Hobbs, Legacy) for hand quilting. It has a nice drape and loft and is very easy to needle. For smaller quilts like wall hangings or cot quilts (cradle quilts) I also use a polyester batting made by Tuscany or Legacy. Hobbs 80/20 or Legacy 80/20 are fine for hand quilting as well and I used them a lot, but the look of the finished quilt is a bit more flat.
I avoid battings with a scrim like Warm & Natural because they are hard to needle - at least for me!
