I am in the same boat you are (I've got a gathered end hammock similar to an Eno) and my ridgeline is a scanty 101" long.
My hammock hangs below the bottom edge of my MacCat Deluxe even with the hammock ridgeline right up under the tarp's ridgeline.
I do have a shorter hammock (and an even shorter one - which I did not like and salvaged for parts) and that hammock is not quite as comfy but is entirely contained in the tarp.
I think I'll be switching to a different tarp for nasty weather, just so I can keep my super saggy comfy hang and not have my butt in the breeze, so to speak.
I need to get out to my favorite hanging park with all my gear and do a lot of figuring about my setup.
