I've quit a lot of experience for this combo.
Did some calibrations.
Rated as 250, and depending off course your method, your lightmeter, your objectif and your camera
(first minute every 10 sec and then every 30" in a small tank)
a good starting point is 7' to 7' 30" by 20°C in ID 1+1!
Printed on Ilford MG IV Warmtone will give you fine results.
