I went into ITMX to rebalance this afternoon. Largely uneventful, all I had to remove was optical table ballast that compensated for fiber-guards missing from the wire-hang, and everything went right to where it belonged. The ISI is now re-locked, and SUS's optic covers are re-installed. ITMY won't be so easy, because it is missing the compensating ballast. When we re-balance, it will have to be done by removing weight from the sides of stage 2. I would prefer we did that before we jammed the ACB in there, if at all possible.
