I would not recommand warm and natural. It is difficult for some to hand quilt. In reading posts it appears that experienced hand quiltrs do make it work. However since you have indicated you have only quited one quilt. Don't make it more difficult on your self by using the W&N. Get a thinner poly batting or one of the poly/cotton battings that are thin. And Yes it will definitely be more difficult to hand quilt over all those seams.
