I'm new to hammocking and I've got a Kammok Mantis and a 20 degree HG Economy Incubator for an under quilt. I get a significantly flatter lay with no under quilt. With the under quilt, it's not uncomfortable, but it is not nearly as comfortable of a lay as without the under quilt. Is that normal, or are there some adjustments you guys would suggest to get an equally flat lay with the Incubator?
