I did locate the date for another thread but I'm blowed if I can find it now.
23 was used quite frequently during strong SW winds and there was some surprise when it was closed. It could be a bit of a pain from an ATC point of view, especially after the ILS was decommissioned and we had to do SRAs all day! However, pilots of 707s and DC8s naturally preferred to use it when the main runways had croswinds! Pilots of other aircraft often stayed with 27L, creating interesting situations for trainee radar controllers - and some experienced ones who had never seen that configuration.
When a single aircraft was being sequenced for 27L, calculating its track distance to fit a "gap" left in the 23 stream was somewhat of a black art with the significantly different groundspeeds due to wind effect. Convincing a trainee that the "following" aircraft on 23 had to be ten miles from touchdown at the same time as the "one ahead" on 27L took some doing!
Tower controllers had problems with 27R departures as vortex effect had to be avoided with traffic on short final for 23.
