This post should have been made a while ago, but doing it now for record keeping.
Back when we were setting up the ITMX HWS, we swapped out the SLED to see if that may solve one of the problems we had. At the time we couldn't entirely tell if it helped or not, so we left it in. I had planned to swap it back when we got to a stable alignment, but I feel like that may just cause problems where we currently don't have any (if it ain't broke, don't fix it). I will keep this used one around as a "used spare" for the future.
