I have the Studio and rag die and my opinion is to use Studio dies with your cutter. To cut all those layers of flannel, the Studio die would be a much better choice. The purpose of these cutters is to save time and if you're taking twice the passes and twice the time to set the fabric up for cutting, I don't see a benefit there. Wait for a 40% off sale at Accuquilt and get the die that's made for your machine.
