Fuji X-ray film: development and EI rating?

[Ari]

Hi,
I have a package of Fuji Rx-U blue-sensitive X-ray film, and was thinking of using a either HC-110 dilution H or caffenol developer.
Can anyone recommend a starting point for EI and development time?
I'm completely in the dark as to this film.

I've searched the very impressive X-ray thread, and liked what I saw from caffenol developers, it seemed like the development was smoother and gave somewhat richer tones.
However, I do have lots of HC-110 on hand.

Any help would be greatly appreciated.
Thanks in advance.

My trials have been with Brand X blue.
For your first pass, assume it's Plus X or similar
Unless you can get a specific answer

Thanks, Ed; that's a good starting point.
I've heard of EIs from 25 to 400.

I shoot mine at 100,seems to work well for me, process in d76 1:4, usually for about 8 to 10 min. i develope it by inspection, negatives look pretty good. good luck

Thanks, John, I stopped using D-76 a while back, but 100 ISO is a good place to start.
