You have to take into account: absolute sensitivity in the IR-Region and size availability and put this in perspective with the offer of monochrome films with IR-sensitivity and make your decision.
I mailed Agfa-Gevaert a year ago and they replied swiftly with a great offer for ten cans of 70mm IR Aviphot BW film. For a variety of reasons (non-EU European customs back then being one), I didn't take them up on the offer. This month, no reply to several mails, sent through same channels as previously. Hopefully the strike didn't ruin such nice company communication.
One major labour union called for this strike and succeeded in stopping production. It ended this morning
The union accuses Agfa management not to follow mutual agreements.
The other union at Agfa did not share that view and did not call for that strike.
