Don't forget FL120 HH/HI/LF inbounds from the West !!!
Also it would make life difficult for TC SW if you fell through our ceiling (FL155 or FL175 depending on where) in the middle of the sector screaming for descent into HOLLY. KK inbounds from the north are transferred to TC SW from MIDLANDS sector descending to FL150 way before our sector boundary but we cannot descend them without back co-ordination hence the long stay at FL150 even if there isn't much else going on. It ain't perfect but it works !!!!!!!!!!
