  2. Instead of current shunt, we will change to use an AOM for the fast power stabilization actuator.
  3. We may decide to use a DC coupled servo, with a remotely programmable offset point to be more like the aLIGO system.
  4. Move the reference cavity and its optics to a different pickoff point.
  5. Move the ISS to the end of the PSL table.
  6. Re-engineer the optics for the PSL_POS and PSL_ANG QPDs.
  7. New EOM for triple modulation.
  8. Change the FSS modulation frequency?
  9. Change the FSS RFPD to have a low Q?
