Nowadays I have settled on 5500° for most off my work, and is rarely changed (this may change overtime, who knows..) YMMV.
Thanks Rudi - I did wonder about setting it somewhere between the two recommendations, but for now am happy with how things are going with it at D50 so will leave it there (at least until the next recalibration).
