i always take 53 to nex, i always take the citaros because the
citaros seem to come at the right time.
Once on a trip on 6013A I happened to meet an uncle who
seemingly had alot of time cos he keep taking 53 from BIS
CGABIS again... Quite the contrast from u, he
always skips Citaros and waits for EEVs instead... He even named a
few that, in his opinion, were good KUBs such as 8608X,
8609T.
