ITM Suspensions
The ITMs are being changed into SOS. For this we will need to fab 2 SOS towers. We will re-use existing OSEMs and misc in-vac hardware.
SOS Updates (Mostly ITMs, but where applicable, extra parts for other new Optics):

Tip/Tilt Suspensions
For the PRC/SRC folding we will use Tip/Tilt stages modified to be used passively. No active damping, no coil drive. Just magnets and natural eddy current damping.
MC
We will re align the MC suspensions so that we are centered on the mirrors this time.
Others
The PRM, SRM, and BS will remain SOS. No new towers.
The ETMs will remain MOS. No new towers.
