I like Hobbs 80/20 batting (not the fusible version). It's a very nice soft, but slightly puffy, batting that is good for either hand or machine quilting. Washes up beautifully.
Connecting Threads has it on sale this week, with free shipping if your order is more than $50. A king-sized batt, which is 10 feet wide by 10 feet long, is $21. Here is a link to it:

Do you mean you are using Warm and Natural batting? I Googled Warm and Gentle batting and couldn't find it. If you are accustomed to Warm and Natural, you will find the Hobbs 80/20 softer with a better drape; however, it will need closer quilting. W and N allows quilting lines up to 10 inches apart; Hobbs 80/20 is more like 4 inches apart.
