I started with a DD too mate, and had similar problems to yourself (despite trying to hang it numerous ways and sleep on the diagonal).
The Superfly is an excellent piece of kit. It give you just the right amount of coverage, packs away very small and weighs very little indeed (not to mention that its a caternary cut too!). Mine is in a dark olive brown colour and is surprisingly camouflage.
Like anything handmade, the goods can be a little 'individual' where the stitching may not be 100% straight etc but all in all, its worth every penny.
