Having used the two rolls of Dural CI that I got as a trial, I have to say I'm very impressed with it. The product is lighter and easier to handle compared to Ditra, and I really like the idea of the mesh on top for improved grip of the addy to the membrane. The end of the roll tends to curl up, but that's not a major problem. So once I've finished my last few rolls of Ditra, i'm a Dural convert.
