Pick one roughly equal to the resistance of the sensor at its midrange temperature. This is not horribly critical, so just pick the closest commonly available resistor. To see the effects of bias resistor selection, run EasyTherm to generate new .inc tables, and compare them with a text editor ...

Got it, took some time but with a little reverse calculating and with good temp/resistance pairs one can use easy therm to figure out the best match of bias resistor to be used.

Can you share that calculating formula with the rest of us?
