I think that you will find the wool blanket pad needs some sort of stabilization, or it will collapse in use. Think of what is going on here: Slippery hammock, curved surface-like a canoe or elongated bowl, and some natural movement of the user. Those are some reasons that a 1/8" GG Thinlight pad and my fleece poncho don't work inside the hammock. Now, if you sew or otherwise attach your wool pad to a nice, stiff piece of Reflectix or truck windshield reflector, that may work quite well inside your hammock.
