I think they will use the 2 citaros and 1 KUB. Because they
might save the remaining KUBs for other svcs that has a high chance
of turning WAB eg. 159.
Plus SBST's WAB quota is 60%
They swap with 83 citaros to meet the WAB quota.According to
SGWIKI,SBS 6053J and SBS 6054G is now perm 85,swap with SBS 905R
and SBS 1957J.
