In this presentation we discuss the first energetics and implosion symmetry experiments using tungsten-based double shells, present first observations of W/Be gradient shell implosions that are predicted to enhance high-mode stability over bare W or W/Be bi-layer designs. Finally, we will present future plans and directions for high-Z double shells.
