Then that's why you're not finding the asym angle that you want at the stated ridgeline lengths. You just don't have as much fabric to spread out.
I would try decreasing the ridgeline length by about 3-4 inches, and see if you can find a comfy spot with that much sag.
If not, you may need to try a mini-spreader bar configuration on the end, and lay more in-line. Perhaps even using something as a pillow under your knees.
